Bug Description

I have a recurring problem where kmail fails to finish updating an imap change after accessing any email with a .ics file attached (calendar invitation). I can fix this by loading akonadiconsole and clearing the akonadi cache and restarting the server; however 100% of the time it crashes when the akonadi server is stopped before it finishes restarting it. Choosing stop server is enough to elicit the crash.

When run from a console, these are the error messages I get:

I've tried to report the bug as a kde bug but there are no associated debug symbols for the akonadiconsole package and kubuntu-debug-installer finds nothing for the /usr/bin/akonadiconsole binary.
