I've been having this problem for about the past year, oddly enough around the time I started using ntpd daemons on all my machines to keep there clocks synched. The same behavior happens on both my home computer (custom built AthlonXP), my laptop (Dell Latitude D600, P4) and my workstation at work (Dell Optiplex GX400 P4), all running Gentoo linux with Gnome 2.6.2-r1 with Nautilus 2.6.3. In fact, the problem started occuring while I was running Gnome 2.4. I do not have nautilus set to draw my desktop (hate desktop icons) on any of the machines. The problem occurs intermittantly, and only a reboot will get nautilus to load properly. A majority of the time, nautilus will not work as soon as I log in, but I have noticed a few occasions where I will close all nautilus windows then try to reopen nautilus later, where the same behavior is displayed. When launched from the shell, I get no errors of any kind. I've recently having a nautilus window set to open when I log in, and this has reduced the number of incidents where nautilus will not open. Reproducible: Sometimes Steps to Reproduce: 1. Reboot computer. 2. Login into X with Gnome desktop 3. Open terminal, type nautilus at the prompt. Actual Results: Nothing. No nautilus window. No errors on the terminal. Shell prompt never returns. Expected Results: Opened a nautilus window. After this had happened again yesterday I finally decided to write up a bug about this behavior. The only Gentoo forum post I've found with anyone else describing this behavior was: http://forums.gentoo.org/viewtopic.php?t=194768 I performed 2 stack traces, one from my workstation where nautilus doesn't appear (output.notlaunching.txt), and one from my laptop, where it does (output.launches.txt). I'm attaching both. When nautilus doesn't launch, the first cloned process (pid 23864) appears to be stuck in a loop during a poll() call. This all happens around line 5309 in output.notlaunching.txt and similar events around line 4952 in output.launches.txt. I'm not a developer so I won't presume to further describe or theorize about what's happening there.

its probably more interesting to attach gdb to the 'hanging' nautilus process & get a backtrace. You have to recompile nautilus with debugging info. Also you should always provide your 'emerge info' with a bugreport, like the bugform states.
Here's my 'emerge info': Portage 2.0.50-r11 (default-x86-2004.2, gcc-3.3.4, glibc-2.3.3.20040420-r1, 2.6.8-gentoo-r3) ================================================================= System uname: 2.6.8-gentoo-r3 i686 Intel(R) Pentium(R) 4 CPU 1.80GHz Gentoo Base System version 1.4.16 distcc 2.16 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled] ccache version 2.3 [enabled] Autoconf: sys-devel/autoconf-2.59-r4 Automake: sys-devel/automake-1.8.5-r1 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O2 -march=pentium4 -funroll-loops -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.2/share/config /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=pentium4 -funroll-loops -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache distcc sandbox userpriv usersandbox" GENTOO_MIRRORS="ftp://ftp.ussg.iu.edu/pub/linux/gentoo ftp://csociety-ftp.ecn.purdue.edu/pub/gentoo/ ftp://gentoo.netnitco.net/pub/mirrors/gentoo/source/" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://spout.ussg.indiana.edu/gentoo-portage/" USE="X acpi alsa apm arts avi berkdb bitmap-fonts cdparanoia cdr crypt cups divx4linux dvd dvdr encode esd evo foomaticdb gdbm gif gimpprint gnome gnutls gpm gstreamer gtk gtk2 gtkhtml imlib java jpeg kde kerberos krb4 ldap libg++ libwww lzo mad maildir mikmod mmx motif mozilla mpeg nas ncurses nls oggvorbis opengl oss pam pcre pdflib perl png python qt quicktime readline samba sdl slang spell sse ssl svga tcltk tcpd tiff truetype x86 xinerama xml2 xmms xprint xv xvid zlib"
Created attachment 40615 [details] gdb backtrace of hanging processes Here's the requested gdb backtrace of the hanging processes.
the backtrace is pretty useless as it is, you have to set 'debug' in USE & recompile nautilus for a start i guess.
Nautilus was compiled with debug flags in the last backtrace I submitted, and "etcat -u nautilus" verified that. Just in case, I reemerged it with "USE="debug" emerge -va nautilus" after verifying that the debug flags were being picked up. I even remerged a second time with the FEATURES="nostrip" option as suggested by the output of "etcat -u nautilus". On both occasions, the backtrace results were similar to the first submitted gdb backtrace log. I'll attach the last backtrace log. Perhaps I need to reemerge one or more of the libraries gdb is loading symbols from (or failing to load since they are not emerged with the debug flag) using the debug flag?

I got the same behaviour after upgrading to gnome-2.8. Starting nautilus from a command shell gives nothing. I ran strace on the process and it is waiting on a futex.

Quick fix: stopping d-bus seems to fix the problem. After /etc/init.d/dbus stop, nautilus starts without any problems.
@ comment 9 & 10 : File another bug, because the reporter is using gnome 2.6, so not using dbus. Also, try to get some debug info from dbus, what it is hanging on obviously... @ reporter : with that backtrace we still can't do much, i guess you'll have to build more (system ?) stuff with debugging info. In the initial report you mention it started when you started to use a ntpd daemon, if you disable this daemon does that influence the behaviour ?
I tried not using ntp, and didn't have any problems, but then again, the problem was so intermittant, I wasn't sure there was a relationship. I'd rahter fight with nautilus and leave ntpd up so all my machines are time-synched (call me anal). Regardless, I've switched my Gnome desktops to have Nautilus draw the desktop, just not show any icons, which seems to prevent the problem pretty well. That keeps a nautilus process spawned early and always around. I've switched the status to Resolved: WORKSFORME, as: 1) this seems to be a problem unique to me 2) I don't ahve the time to rebuild every library with the debug flag 3) I've got an acceptable workaround Cheers everyone...
