Description C 2012-01-12 14:27:37 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 x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

Closing Inkscape - but also happens randomly when closing Gimp, Firefox and other applications.  Only started a few weeks ago.  Not sure if related to installing pppoeconf - I also did that at a similar time.

The crash can be reproduced some of the time.

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

New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.7.3 (4.7.3) using Qt 4.7.4

- What I was doing when the application crashed:
Closing a Window causes the Desktop to crash and restart.
It doesn't seem to matter which application I close.
