Bug 264352

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I turned the computer on, after the KDE splash screen disappeared and the desktop appeared, an error box came up saying that plasma shell had crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
