Sorry that I am continuing to add things that may or may not be related.  Over the last couple of days, KMail has started freezing when I try to refresh my e-mail manually after deleting a couple of mails (in order to get back the entries which have disappeared).  CPU usage roughly 50%, constant memory usage of 3.8%.

I took a backtrace of Kontact in this frozen state (I currently only have limited debugging information available):
