Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic x86_64
Distribution: Ubuntu 12.10

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

Drag "Icon-only Task Manager" widget to the default panel. The mouse cursor displayed with a red circle.

- Unusual behavior I noticed:

The cursor stayed the same (with the red circle) and the desktop seemed to freeze

The crash can be reproduced some of the time.

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