I was stuck recently after a semi-failed upgrade.  After messing with the 
akonadi database for a few hours I finally just shut akonadi down ('akonadictl 
stop'), removed ~/.local/share/akonadi ('rm ~/.local/share/akonadi') followed 
by a start ('akonadictl start').  The start will see that the database is gone 
and rebuild it from scratch.

I ran into some strangeness - the filters all lost their destination folders, 
the order of the folders was off (only really mattered for the pre-defined 
ones, I think some code uses the index rather than the name) and maybe some 
other stuff.  But it was a lot faster that my messing with trying to manually 
mount and upgrade the mysql db.
