Randomly. I can reproduce this pretty reliably now by enabling slideshow in
Geeqie, setting delay to 0.2s, letting it run for 15 mins or so. If you need
some more information about the crash, I can provide.

Indeed, after upgrading to kernel 3.15rc8 and git firmware, I can no longer
reproduce the issue. It's been running without problems for 45 minutes now.
