I had a very similar situation about a month ago, posted it to the mailing 
list , as follows ..

------
Running Kmail 1.13.2 and KDE 4.4.2, with Ubuntu 10.04 , all updates applied.

KMail is constantly freezing, one instance where a process called virtuoso hit 
400% ,a dn there were many nepomukservices running and other nepomuk 
processes, all eating up a LOT of CPU.

It's at the stage now that I can't reply to any messages, it just freezes, so 
even this may not get through.

I looked in the package manager, does Kmail depend on nepomuk?? or virtuoso?? 
at all, I'd rather uninstall them.
