Bug 300006

Application: kmail (4.8.3)
KDE Platform Version: 4.8.3 (4.8.3) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.3.4-gentoo-Saberhagen x86_64
Distribution: "Gentoo Base System release 2.0.3"

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

kmail2 is crashing after every startup. The window opens and kmail opens the akonadi-resources and then it suddenly crashes.

It worked fine for month without a problem, then since yesterday it just crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
