I get this some time, mostly when I migrate the kmail directory to a new 
installation, or after a crash. Never enough to be a trouble.

I imagine you've done this allready, but what I do is delete all the files 
in .trinity/share/apps/kmail (not the directories, of course) and restart 
kmail, which re-indexes everything. I usually get a few unread messages which 
I "reread", then it's done.
