Bug 261477

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic i686
Distribution: Ubuntu 10.10

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

I was adding some recently downloaded widgets. The specific widget which I was trying to add while the workspace crashed was GnoMenu  which also showed some error regarding some script initialisation failure. 

Custom settings:
Plasma workspace was configured to show separate widgets for each virtual desktop. There are total of 4 configured virtual desktops.

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