-- Information about the crash:
this started yesterday on 4.4 branch. while I'm composing a message, kmail often locks up. the UI still draws (without composite), the cursor blinks, but it's completely unresponsive. it's happened on... I think all but two of the emails I've written today. so it's kinda severe.

this latest one happened just after I hit the send button - the message window went grey the way it does when sending, but never went away.
the backtrace dr konqi picked up here is from running kquitapp kmail, and might not be much use; I got a backtrace out of gdb before making kmail crash (two actually; identical. it's really stuck.)

I think it *might* have frozen once while just reading mail, too.

here's the gdb backtrace:
