If I send an email message (either with "Send" or Cntrl-Enter) and then don't wait long enough before clicking on a folder on a different IMAP server, kmail crashes.

That is:

1) Write email as Account A
2) Send
3a) Wait 5-10 seconds, click Inbox on Account B -> Everything is fine
3b) Wait < 5-10 seconds, click Inbox on Account B -> Kmail crash

The email is always sent, though.
