Installed from:    Fedora RPMs

Was just reading mail via IMAP (was in the middle of reading a new message or selecting the next unread message) when I think an automated mail check led to a crash.  All the new and unread messages in the folder disappeared, and KMail tried to grab them all again (I saw it grabbing each one via the status window) then crashed with this backtrace.
