Bug 279262

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.00 (4.7.0) (Compiled from sources)
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:
plasma desktop crashes every time I perform a search in kmail2. This happens with kde 4.7.0 from kubuntu and akonadi, kdepim* from git master.

The crash can be reproduced every time.

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