Thumbnail Crashes

I seem to be getting fairly frequent crashes on starting up Dopus. There is a screenshot here with some context included. It is not a great problem since on re-starting it ususally works ok. It does seem to be connected with folders of thumbnails.

Incidentally, it's great having the folder tree in ftp - what a difference it makes.

See the FAQ about crashing when viewing certain folders for advice on tracking down which component/app is causing the crash.
