Please describe the problem:
When nautilus is trying to automaticaly renerate a thumbnail-view of a 'previously-not-completed' JPEG nautilus uses all available CPU power and never stops. Even after closing this particular folder.

This happens for instance upon completion of a torrent. It's hard to regenerate but it happens every so often. (to me, around 3 times per week, but I download lot's of torrents)
Upon restart of nautilus that particular thumbnail renders just fine.

Steps to reproduce:
1. Did
2. not
3. found
4. out
5. yet

Actual results:


Expected results:


Does this happen every time?
Every so often. I can't intentionally regenerate it.

Other information:
This time it happened upon completion of a JPEG (117kb) that is part of a partially downloaded torrent (70% of 2,2 gig).

So this JPEG was complete, the rest of the torrent wasn't.
