-- Information about the crash:
Under Windows 7 (64 bits):
- I updated KDE to the last KDE release (4.8.0):
- I opened Dolphin.
- I enabled "Preview" to be able to see the previews of images on the icons &
2-3 seconds later I get the crash window about kio_thumbmail.


If I disable the preview & re-enable it again the crash always happen.

The crash can be reproduced every time.
