Comment 1 Akhil Laddha 2010-06-02 04:04:46 UTC

Thanks for taking the time to report this bug.
Unfortunately, that stack trace is missing some elements that will help a lot to solve the problem, so it will be hard for the developers to fix that crash. Can you get us a stack trace with debugging symbols? Please see http://live.gnome.org/GettingTraces for more information on how to do so. Thanks in advance!

Comment 2 Callum McKenzie 2010-06-13 10:46:53 UTC

The recursive call to init_pixbufs looks deeply suspicious. I'm looking into it. It is quite probably related to bug 464043 - although that doesn't have a recursive call to init_pixbufs. Bug 480555 may also be related.

Comment 3 Callum McKenzie 2010-06-14 05:59:49 UTC

The crash is caused by a double-unref in init_pixbufs. Fixed in master.

Comment 4 Callum McKenzie 2010-06-14 07:24:51 UTC

Also fixed in gnome-2-30.

Comment 5 Callum McKenzie 2010-06-14 07:30:52 UTC
