Ah, probably goes without saying, but KMail seems really twitchy during start 
up when rebuilding (or loading?) its indexes.  Basically check top to see if 
it's finished.  On my system it'll suck up a full CPU for 5 to 20 minutes and 
is almost guaranteed to crash if I try to do anything in KMail until it's 
finished.
