Bug 303971

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: Tried to close Skype and it became unresponsive refusing to close.  When forced terminate of Skype (when pop-up dialog offered that option) then Plasma Desktop crashed.   I have had Skype refuse to close properly like this before, but termination didn't crash Plasma desktop.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
