Description abelius 2011-08-28 20:43:24 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I was using Miro and the desktopgrid. I could exit the grid without problems but the Kpanel and all widgets stopped responding after which it crashed. This system was freshly booted (not resumed from suspend).

The crash can be reproduced some of the time.

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