Bug 268802

Application: kontact (4.4.9)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic x86_64
Distribution: Ubuntu 10.10

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

Just try to launch kontact after updating packages

- Unusual behavior I noticed:

KWallet asking for passwords of my mail accounts again, although they usually are stored.

So: After upgrading packages and the next start of kde, KWallet forgot my passwords and kontact crashes on startup (don't know if these two symptoms are related).

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
