Suddenly, after updating some system packages, firefox and thunderbird stopped working (got a SEGFAULT right on startup). I really tried hard to find find the issue and I came to this: when libgnome is installed, they fail, if I unmerge it (and remove "/usr/lib64/libgnome-2.so.0*"), they both work. Maybe the root cause is somewhere else but this is as far as I got. Another user seemed to have the same problem: http://forums.gentoo.org/viewtopic-p-6983838.html backtrace and emerge --info will be appended Reproducible: Always

Created attachment 305953 [details] gdb backtrace with debugging symbols Firefox not built with debugging symbols due to time constraints. I saw gnucash trigger this, too but now it won't start at all since it won't start w/o libgnome (in contrast to firefox)
Looks something related with /desktop/gnome/sound, maybe because of esd support removed? :-/
Are you able to reproduce on a new created user account with a new home?

(In reply to comment #14) > Please attach the file(s) in your ~/.gconf/desktop/gnome/sound This bnug has nothing to do with sound issue. Esd is not required and has been patched out of both thunderbird and firefox. With the use of so many overlays, we could have a bug that is invalid due to a lib being included that is not part of official tree that is breaking libgnome support.
Created attachment 307481 [details] output of "eix -I -J" Sorry that this is quite verbose. It is a list of packages that have been installed from any overlay I'm using (using "eix -I -J"). If you think any package in that list might interfer with firefox/thunderbird/gnucash/libgnome-stuff, please tell me and I'll uninstall and retest.
I am having the same issue and also using gcc 3.5.4 on amd64 (I have an older kernel, though: 3.2.1-r2.). In addtion to firefox, balsa is also affected. $ gdb balsa GNU gdb (Gentoo 7.3.1 p2) 7.3.1 Copyright (C) 2011 Free Software Foundation, Inc.

I had portage-2.2.0_alpha95 installed at the time. I have since upgraded to portage-2.2.0_alpha99. I have tried glib-2.30.2 and glib-2.30.3. No difference: same segfault either way. I have found an interesting clue: All broken packages work if I: emerge --unmerge gconf firefox and balsa will present and error "An error occurred while loading or saving configuration information for balsa. Some of your configuration settings may not work properly". If you click "OK" on this error both applications run fine. If after that, I run emerge -1 gconf everything goes back to broken (segfault in /usr/lib64/libglib-2.0.so.0). (Using gconf-2.32.4 and I just got the same results with gconf-2.32.3, but I did not rebuild other packages after installing 2.32.3). I have repeated these steps several times with the same result every time. Not having gconf installed seems to skip the initialization steps that cause the issue. I will be running without gconf installed in the short term. I ran the above tests with balsa (because I am using firefox to compile and post the results). Firefox exhits the issues the same way. I have confirmed that it always works with gconf uninstalled and always segfaults with gconf installed. jannis: Can you try emerge --unmerge gconf and see if that "fixes" the issue for you? $ emerge

Have you tried to set your locale to "C" or english?
Just a short test with gnucash (used to crash, too) showed: After unmerging gconf, it doesn't crash anymore. Still don't know where exactly the cause is... libgnome or gconf :/

Ah wait, I have a full system backup from 20120316 so I'll try starting from that. Maybe in a virtual machine :)

The breakage happened before this build completed. From what I could tell using the system as things compiled, firefox broke at the moment the it was emerged. I noticed the breakage the next time I started firefox, which was within minutes. I had also started firefox a few minutes before the emerge (while it was still compiling) and it worked fine. I was not using the system when balsa was emerged, I cannot pinout its breakage as accurately. Let me know if you need any more details.
Created attachment 308205 [details] 1.png Looking to: https://bugs.launchpad.net/ubuntu/+source/gnome-utils/+bug/284923 looks like crashes like this would be caused by wrong gconf options, offending one looks to be: /desktop/gnome/sound I attach you what I see from gconf-editor in my systems, compare it with yours

(In reply to comment #33) > Created attachment 308221 [details] > gdb backtrace of gconf-editor > > Forgot to tell portage not to strip debugging symbols via FEATURES I have the exact same result. Here are my exact steps: 1) launch gconf-editor -> Window appears 2) On the left panel, double click on desktop -> gnome appears under desktop 3) double click on gnome. 4) Single or double click on any item *except* sound -> settings appear on right pannel 5) Single click on sound -> program immedately segfaults. Settings on right do not change, highlight does not move to indicate sound active. Segfault is immediate.

I repeated the gconf-editor test with a new user starting with a (nearly) empty home directory (no .gconf or .gconfd). 1) Start gconf-editor Window opens and the following error is printed: (gconf-editor:10741): GConf-CRITICAL **: Received list from gconfd with a bad list type GConf Error: Type mismatch: Expected list of String, got list of UNKNOWN, 0 2) Double click on desktop gnome appears under desktop 3) Double click on gnome Gnome expands to many sub-items 4) What happens next depends on which sub-item is selected. The following sub-items display settings on the right panel: thumbnail_cache typing_break The following sub-items print an error to the terminal and display no settings on the right: background font_rendering interface The following sub-items immediately segfault: fileviews sound Perhaps something is wrong with my system gconf settings? Where are these stored and what package sets them? Or does each package install its own system defaults?

I do: ekripton@miramis ~ $ eix -e gconf [I] gnome-base/gconf Available versions: (2) 2.32.3 2.32.4 (~)3.2.3 (~)3.2.3-r1 {{debug doc +introspection ldap (+)orbit policykit}} Installed versions: 3.2.3-r1(2)(10:16:11 11.04.2012)(doc introspection policykit -debug -ldap -orbit) Now having gconf with -orbit I tried running media-sound/grip (that hard-depends on orbit). It works but according to strace doesn't use orbit at all (but it does IPC using dbus).
(In reply to comment #44) > Building gconf with USE="-orbit" (which is default by now) fixes the issue > for me. See also https://bugs.gentoo.org/show_bug.cgi?id=411237 comment 5 I had been using gconf-2.32.4 which does not have an orbit use flag. I noticed that there is an unstable gconf-3.2.3-r1 in the tree. I emerged that with USE=-orbit (default) and the problem is fixed.
(In reply to comment #45) > Are you both using gconf-3? I was not. I have upgraded to gconf-3 with USE=-orbit and the problem is fixed. Thank you for sticking with us to the end, Pacho Ramos.
Does anything speak against closing this as RESOLVED FIXED?
But, does it still fail with USE "orbit"?
(In reply to comment #50) > But, does it still fail with USE "orbit"? Oh, you're right - it still fails (just tried again) so it's not FIXED. The workaround USE="-orbit" is just the default now so fewer people might hit this bug. What still might cause trouble is that gconf:2 uses orbit and can't be stopped doing so via USE-flag (according to the reports by Marathon
I have been fighting with this issue for a day now. I am wondering why the status of the bug is UNCONFIRMED? Anyway, I'm glad I'm not alone - I was beginning to suspect hardware failures. Here is a backtrace of gconfd-2 while trying to start evolution, which crashes as well with segfault (from a strace it seems none of the gconf-relying apps check that the socket they open to contact gconf is closed externally - but I'm not familiar with the code at all). cipi@pink ~ $ gdb /usr/libexec/gconfd-2 GNU gdb (Gentoo 7.3.1 p2) 7.3.1 Copyright (C) 2011 Free Software Foundation, Inc.

I've been having this same problem after cleaning my USE flags and recompiling my system. It's affecting both firefox and gnucash. My firefox backtrace is the same as above. Francesco Riosa's patch fixes it. Commenting out the following line: <entry name="theme_name" mtime="1340736979" schema="/schemas/desktop/gnome/sound/theme_name"/> in /etc/gconf/gconf.xml.defaults/%gconf-tree.xml also prevented firefox from segfaulting. I'm still having problems with gnucash. When I start gnucash, everytime, it displays the window saying "Cannot find default values." It then proceeds to start a configuration druid giving me the option to "Update the search path" or "Install into home directory." Updating the search path segfaults in liborbit. Installing into my home directory calls /usr/bin/update-gnucash-gconf multiple times, each time segfaulting. Also after some time, gconfd-2 begins to use an excessive amount of CPU time, between 60% and 100%. # Relevant packages app-office/gnucash-2.4.10 gnome-base/gconf-2.32.4 gnome-base/orbit-2.14.19-r1 dev-libs/glib-2.30.3::local # Francesco Riosa's patch applied

Have you tried to run: gconftool-2 --unset /desktop/gnome/sound ?
(In reply to comment #61) > Have you tried to run: > gconftool-2 --unset /desktop/gnome/sound > ? Pachos, I'm not a C language expert but it should not crash for an empty string anyway, so a fix is advisable. Never mind that kde users (which use firefox) would never be able to assemble that gconf command. cheers, Francesco

The problem (as shown in c#54) is that "g_utf8_validate" should (would say MUST) NOT crash if the ConfigValue parameter contains a null string. A better solution could be to print a warning and possibly a trace to find the wrong value, but never ever crash, as demonstrated by the fact the values are not yet known it's not even an informative crash.
(In reply to comment #64) > The problem (as shown in c#54) is that "g_utf8_validate" should (would say > MUST) NOT crash if the ConfigValue parameter contains a null string. No. The creators of glib believe that it's the caller's responsibility to make sure that functions like g_utf8_validate() are never called with an invalid parameter type - and while NULL is a valid character pointer, it's considered to be invalid as a C string. See https://bugzilla.gnome.org/show_bug.cgi?id=652526#c4

See > https://bugzilla.gnome.org/show_bug.cgi?id=652526#c4 From a user experience standpoint, would it make sense to just patch g_utf8_validate and then have a blocker for removing that patch when all the offending callers are fixed? If things are breaking for users then we either need to keep this masked or work around it. Sure, maybe the problem is that every other package is broken, but our users just care that things work or they don't, and we can't fix every other package overnight. Otherwise, normally I'd say follow upstream.

Alternatively, maybe gnome-base/gconf-3.2.5 could be stabilized. Pacho, are there any problems with using gconf-3.2.5[-orbit] in gnome2?

it's possible at least to craft a tool that check *consistency/goodness* of the xml files? mind you all are well formed xml, what the tool should find are the occurences of bad values, for example empty corba string values. Then ship it with gnome-base/gconf upgrading to gnome-base/gconf-2.32.4 I've forgot to apply the patch and wasted time again. Then re-installed it to 3 boxes that stopped working. This bug stopped to be ridiculous too much time ago.

Would have that changed anything? Pacho, respect for upstream decision is a good thing, but sometimes, you just need to do the "right" thing. IMO the right thing is to NOT let ONE error in hundreds of KB of config files fuck half of a system (if possible), then hurry up to stabilize a "sane" version of glib and forget the hack. monfi ~ # LANG=C gconftool-2 --get /desktop/gnome/sound No value set for `/desktop/gnome/sound' monfi ~ # LANG=C gconftool-2 --unset /desktop/gnome/sound monfi ~ # LANG=C gconftool-2 --get /desktop/gnome/sound No value set for `/desktop/gnome/sound' emerge -1 --usepkgonly dev-libs/glib::gentoo >hom>viv>Imm>work$ firefox Errore di segmentazione emerge -1 --usepkgonly dev-libs/glib::vivo firefox "https://bugs.gentoo.org/show_bug.cgi?id=408857"
