Lots of problems with update

Hate to say it, but pretty bad experience here with kde4.1 update.

1. kmail.  I use dimap.  Lost all my mail.  Have to resync caches.
    Crashed when clicking on 'expire' to set expiration.
    Lost all my mail subscriptions.
    Lost all my accounts.

2. akregator.  Crashes all the time.  Unusable.

3. amarok.  Doesn't play anything (this is the alpha).  Reverted to 
amarok-1.4.9.1 OK.

4. Had to turn off desktop effects, otherwise kwin was using 100% cpu.  Was 
pretty bad under 4.0.5 - but I had hoped it would be better, not worse!
