Bug 273578

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I was watching a movie with VLC, using internet with Firefox and working with Vi into Konsole.
- Unusual behavior I noticed:
I was listening music with amarok then I close it. It's icon still remain in the notification plasmoide. So I decided to kill amarok with pkill -9 amarok. Then Plasma crashed. When it re-opens, the amarok icons disapeared.

-- Backtrace:
