Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.1
Operating System: Linux 2.6.35.11-83.fc14.i686.PAE i686
Distribution: "Fedora release 14 (Laughlin)"

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

I added the system tray to the menu. I then had two of them open.

I right clicked the new system tray widget, hit remove and plasma crashed.

The crash can be reproduced some of the time.

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