-- Information about the crash:
- What I was doing when the application crashed:
With mouse-over on a folder on the desktop(folder view),I clicked on the arrow on the up-left position showing me the folder stuff and then I tried to delete(shift-del) a subfolder of it.

The crash can be reproduced every time.
