Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: click on menu after boot, it is impossible to go on using menu. everytime it crashes

- Unusual behavior I noticed: it seems frozen

- Custom settings of the application: nothing special

The crash can be reproduced some of the time.

-- Backtrace:
Application: Shell del desktop di Plasma (plasma-desktop), signal: Bus error
