Bug 246953

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 2"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
Was move resizing/moving the Plasmoid "Fancy Tasks", after just adding it, and configuring it(what icons/thumbnails to show), and within minutes, it crashed.
The Crash froze display, lost view of desktop backround, main default widget/icon bar at foot of screen disappeared etc.
As I was loading bug report, Plasma started to rebuild the screen, which it gradually compleated.
I have installed all bug report backend files, in the hope it will be of use.

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