Bug 269147

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Plasma Desktom crashes with no obvious reason. Then it restored.

- Unusual behavior I noticed:
I noticed Amarok to be closed though I didn't do that.

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