Description skierpage 2011-12-15 07:32:26 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:
  I had three Okulars open, one from command-line and two by opening Thunderbird PDF attachments.  I right-clicked on the group in the Plasma panel and chose Close to close the lot, and crash! The Plasma panel bar disappeared.

- Unusual behavior I noticed:
The Plasma bar returned (good!).

The crash can be reproduced some of the time.

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