Bug 414922

SUMMARY
I had a crash of akonadictl right after I had asked a restart of akonadi in akonadiconsole. The reason for the restart was kmail being stuck ‘fetching’ a message. (This is always a sign that there's a problem and closing kmail and restarting akonadi is then typically required to get things working again.)

Backtrace by DrKonqi:
