Bug 266400

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.36.1 x86_64

-- Information about the crash:
I've tested a plasmoid in a windowed mode (maybe it affected the whole Plasma) and changed the virtual desktop with the hotkey, Plasma suddenly crashed.

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