I don't use IMAP, and have mixed folders in mbox and maildir format.
I know, I should move the mbox folders to maildir, and delete the mbox 
folders.

But, as I already mentioned, in breezy kmail worked like a breeze, and 
now every 2 or 5 times I change the folder kmail crashes. I noticed 
that behaviour some month ago after an upgrade. I turned the most 
popular folders into maildir to solve the problem, it helped 
slightly...
