Application: kontact (4.8 rc1)
KDE Platform Version: 4.7.95 (4.8 RC1 (4.7.95)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

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

Kontact was running for a few hours. It crashed when I shut it down via Ctrl+Q.

Akonadi is configured to check two IMAP accounts, where one of them is a Kolab server (and configured as such). The non-Kolab IMAP account also contains "groupware folders", i.e. a folder where contacts are stored.

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