I've got only a Gmail account setup on Kmail via IMAP.

It just crashed while trying to open the Inbox. It stayed for a few seconds on the 'Retrieving folder contents' message and then crashed with the backtrace below.

When re-opening Kmail, a dialogue came up saying that the app seemed to be already open in another screen. I told it to open anyway and now it works.
