Bug 256209

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.2 (KDE 4.5.2) "release 10"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.5-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
Creating a new activity on Virtual Desktop 6. Added a new default panel on top of screen, but didn't really want that for this activity. When I removed the panel, Plasma crashed, though desktop still appears functional at this  moment.

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