Bug 275754

Application: kontact (4.4.10)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

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

Just starting KDE.
Kontact crashes every time when KDE starts. When it's restarted, it correctly waits until KWallet is opened and can be used without a crash.
Also sometimes crashes on KDE shutdown.
I'm using the latest Kubuntu, 11.04.

The crash can be reproduced every time.

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