Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Turned on computer, opened Kmail

- Unusual behavior I noticed:
Plasma begins crashing. Even if I restart plasma-desktop, within the minute it will crash again. This only seems to happen when I'm connected to wifi (I've tried this one three networks, the one using Ethernet works fine, but the two wifi networks causes plasma to crash.

- Custom settings of the application:
Akonadi was subscribed to a google calendar and google mail account. Now that these accounts have been removed, everything seems stable again.

The crash can be reproduced every time.

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