Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
* Installed pyATImonitor, Radeon Power Management and Sensors-Monitor via hotnewstuff
* added pyATImonitor to desktop
* script initialisation for pyATImonitor failed (this always happens)
* removed pyATImonitor from desktop
* switched desktops
* crash

- Unusual behavior I noticed:
*  Radeon Power Management and Sensors-Monitor do not show up in "add widgets" bar

- Custom settings of the application:
* Dual-screen desktop, desktop switching via shortcuts

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