-- Information about the crash:
Kontact crashed just as I exited it.  Kmail was showing at the time, but I had been using the feed reader during that session.  Kmail may have been busy doing something as I closed it, but I'm not sure.  I use Gmail via IMAP.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
