Starting program: /home/larsi/src/emacs/trunk/src/emacs
[Thread debugging using libthread_db enabled]
A few images, like the following, sometimes segfault Emacs 24:
http://chzichcafterdark.files.wordpress.com/2011/08/funny-pictures-excuse-me.gif
Program received signal SIGSEGV, Segmentation fault.

It isn't 100% repeatable -- with this image, it seems to happen every
third time I start Emacs.
