kino segfaults on startup. It doesn't seem to matter whether it is compiled with 3.3.3-r5 or 3.4.0-r4.

Interesting... I managed to create a patch that comes around the SIGSEGV. They are caused my bad coding: GDKImage{Filters,Transitions}Repository doesnt set its member "selected_{filter,transition}" to NULL. I will attach a patch for this. On the other side, after eliminating this SIGSEGVs, a SIG32 emerge and its backtrace looks very much like the backtrace of the nautilus/gftp SIG32.

Created attachment 32337 [details, diff] Preliminary patch to allow to get the nautilus like SIG32 instead SIGSEGVs for bad kino source code
seems that people are getting this same crash on x86 - see bug #50572 here's another backtrace if it's any help: #0 0x00000000004a58e9 in GDKImageTransitionRepository::SelectionChange() ( this=0xd00238) at image_transitions.cc:505 #1 0x00000000004a59ec in GDKImageTransitionRepository::Initialise(_GtkOptionMenu*, _GtkBin*) (this=0xd00238, menu=0xb10510, container=0x0) at image_transitions.cc:488 #2 0x0000000000494ad1 in PageMagick (this=0xcfd9b0, common=0x98a970) at page_magick.cc:1365 #3 0x000000000046d9f3 in KinoCommon (this=0xcf4220, widget=0xc1ae00) at kino_common.cc:103 #4 0x0000000000496643 in kinoInitialise (widget=0xc1ae00) at commands.cc:148 #5 0x000000000042f6af in main (argc=1, argv=0x7fbffff128) at main.c:157
Herbie, did you use my patch ?
No, that was without your patch. Just re-emerged kino and it now seems to be working. I got no sigsegv or sig32's and it ran perfectly. Not too sure what I've changed on my system that could have affected this. I'm using gcc-3.4 btw.
I still get those SIG32s. I will mail the kino developers about it.
As the kino developer, I just want to confirm that there is a known bug in Kino 0.7.1, which Danny's patch addresses. We have had the fix in our CVS for some time, but it is a little different: I use a member initializer in the constructor: GDKImageTransitionRepository::GDKImageTransitionRepository() : selected_transition( 0 ) and GDKImageFilterRepository::GDKImageFilterRepository() : selected_filter( 0 ) I am working on a 0.7.2 release, so I am trying to reproduce the bug on his machine. So far, with the slowness of ssh X11 forwarding over the net, it is not reproducing.
Ok, those SIG32s only get thrown when you run kino via gdb. Seems to be a bug in gdb that is already being workd on. Patch is in CVS by now.
*** Bug 50572 has been marked as a duplicate of this bug. ***
Please reopen this bug. This was never fixed in kino-0.7.1. People are still complaining about segfaults at start on amd64. See: http://forums.gentoo.org/viewtopic.php?p=1903538#1903538 and: http://forums.gentoo.org/viewtopic.php?t=252484&highlight=kino+amd64 Requesting masking kino-0.7.1 as -amd64 and promoting kino-0.7.5 as + in its place.
reopened per user request
0.7.5 marked stable in cvs as most of the forum ppl report success - I use it just fine (now libdv is fixed).
