-- Information about the crash:
I was in the "starred" gmail folder, and clicked on a message... it was taking a while to load, but I hit 'r' anyways, and it popped up the usual waiting-to-load messagebox. a minute later, I was seeing mail vanish from the starred folder (waah, kmail's gone and unstarred a bunch of random mail again, I need a better imap server). :( another minute goes by, and it still thinks it's trying to load that message, so I click cancel, and it crashes.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
