Bug 248864

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

-- Information about the crash:
Was using a launcher for KOrganiser. Clicked, workspace crashed. Other launchers on bar: Firefox, Pidgin, one I made myself for a bash script to launch a Wine program. 
My mouse is a tad sensitive, sometimes attempts to move launchers around when I click on a launcher instead of opening it.

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