Bug 311273

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-34-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: Attempting to raise the application launcher menu will cause Plasma to close unexpectedly. Occurs in all situations, regardless of whatever applications are running in the background. Menu is in classic mode.

- Unusual behavior I noticed: The menu will freeze for roughly ten seconds, during which point the entire taskbar will not respond. The taskbar and menu close, then the taskbar immediately reloads, along with the Crash Reporting Assistant.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Bus error
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
