Sentry Crash Report:

Description Simon Tutek 2011-12-31 16:38:16 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Was running Eclipse, loimpress, gimp and chromium. When switching windows the WM stops accepting commands (like restore window) and the sceletons of the windows stick on the desktop.

Running kubuntu in vmware 4.1.8.

- Unusual behavior I noticed:
Windows stop listen to mouse events and others, the rendered contents stick inactive on the desktop..

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