Description Jordi Ferrando 2011-12-29 16:18:43 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-pae i686
Distribution: Ubuntu 11.10

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

- Unusual behavior I noticed: Taskbar disappears and appears again. KDE applications are responsiveness

-- Backtrace:
Application: Àrea de treball de l'escriptori Plasma (plasma-desktop), signal: Segmentation fault
