Bug 268799

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.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
1. I tried to move the device notifier widget from the desktop to systray
2. after dragging it to the systray, it didn't remained there, but fell to the desktop again as a widget (strangely drawn)
3. the systray got an extra icon space where should be the device notifier
4. mouse click that empty spot, where now should have been device notifier
5. plasma crashed

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