Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

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

Trying to add Device Notifier to the panel.

- Unusual behavior I noticed:

There was a dark gray rectangle in the panel in the wrong place, I was trying to move it to the correct location but it wasn't working. Then boom.

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