Recently I had a similar experience, in that the bootup sequence never 
finished.  After fiddlingfor a while I did the obvious - renamed ~/.,kde and 
got a clean kde.  I then copied back the essetials such as my mail 
configurations and ignored application and desktop (read desktop effects, 
etc.) altogether.  Those are easily fixed as you come across things.  I've had 
no problem since.  Clearly something had either become corrupted or carried 
over where there was an incompatibility.

Check for updates.  I saw that a while back, but it doesn't happen now, so 
it's almost certainly version or distro-version specific.

Many of those things have already been addressed.  Yes, any database that 
attempts to index everything is going to be big.  The KMail issue, though, I 
consider to be more serious.  I take it that you are using the experimental 
KMail2?  I understand that IMAP and DIMAP have been merged, and I assume that 
that means DIMAP (downloaded) in every case.  I'm not too happy about that
