Bug 330494

Application: akonadi_imap_resource (4.11)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.12.9-031209-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
As usual, kmail was running over night and it's configured to periodically check for mail. In the morning I had a error dialog telling that some account settings are broken and providing the possibility to directly edit account settings. I didn't do that but just pressed 'Check Mail' in kmail.
some moments later I got the crash assistant.

-- Backtrace:
Application: Compuware of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault
