Searches appear to have been the cause indeed. But, here's the kicker, 
no searches were listed under "Searches" in the folder list. I had 
looked there before, because I suspected searches.

There was a "Last Search" file in ~/.kde/share/apps/kmail/search and I 
had to delete that in order to stop KMail's misbehavior.
