Bug 243469

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-23-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
It's just like the title says, I tried adding that widget and managed to do so but I found it not useful so I tried to delete it and during that it crashed. The screen went black and only wicd icon was shown.. Then this crash report window appears to the black screen and a small while later my desktop returns too, although the widget covers my entire desktop, making it impossible for me to click any icons in the desktop folder.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
