Steps to reproduce:
1. pick an image (I used a jpeg, about 100KB, 800x600)
2. run eog <yourimage>
3. as soon as the picture is displayed, hit q to quit (the bug occurs when you quit by closing the window with the mouse, but you have to be fast)

This bug is reproducible but erratic. Sometimes you can do it 10 times and it won't happen. Sometimes it happens 10 times in a row.

Stack trace:
I ran it in gdb and got the following output:

Program received signal SIGSEGV, Segmentation fault.
