KDE Platform Version: 4.6.2 (4.6.2) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: I ran Bleachbit under root (Konsole[Terminal]->sudo bleachbit. When it completed (showing 4 errors the first time and 6 errors the second - I had rebooted the computer, a Toshiba Satellite 1905-S277, between runs), I closed out Bleachbit and then, when I closed the Konsole, the computer crashed.

The crash can be reproduced every time.

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