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:

Every 5 minutes (the check interval of the IMAP account) I got a lot (> 20) of warning messages "<account name>: There is currently no session to the IMAP server available.". To get rid of the problem (which reliably made knotify4 hang after a few occurrences) I wanted to try to stop and start the Akonadi server. When the notification "The Akonadi server has been started and can be used now." appeared Kontact crashed immediately.

-- Backtrace:
Application: Kontact (kontact), signal: Aborted
