Hey Mike,

Try moving your akonadi directory out of the way: 

mv .local/share/akonadi/ .local/share/akonadi_old

And then try starting akonadi again.

Akonadi will rebuild the databases and you won't loose any emails or 
calendars, although you may have to tweak stuff in you email profiles and  
folders, as, when rebuilding, you may discover that Kmail is now saving sent 
message in... oh... the drafts folder or the trashbin... it can be anywhere.

Another thing that may be affected are your local email filters, and, if you 
have more than one identity, the identity associated with each folder.

... Yeah, my setup is a bit clunky.

Cheers

Paul
