Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.5 (KDE 4.5.5) "release 1"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.2-desktop i686
Distribution: "openSUSE 11.3 (i586)"

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

I installed Google Tasks plasmoid from kde-look via the installer inside KDE itself, and everytime I delete the plasmoid it crashes again. It only happens when the plasmoid is added to the pannel, not when I add it to desktop.

The crash can be reproduced every time.

-- Backtrace:
