Comment 0 for bug 1203349

 Occurs when opening a folder that contains a video file that is invalid or a 0 byte file. Nautilus crashes on the invalid or o byte file when attempting to thumbnail instead of just moving past

Test case:
run in terminal -
touch Videos/1.mp4
Now try to open Videos in nautilus

nautilus Videos
