-- Information about the crash:
- What I was doing when the application crashed:

I had multiple issues since upgrading to kmail2, these are the steps leading up to the crash.

kmail2 was complaing 'Cannot determine the UID for the newly created message on the server'. I checked serverside and suspected duplicate X-UID in the (dovecot) mbox file. Since kmail was spamming 10's of these messages, and also seemed to be pushing the whole inbox (or some large amount of mail) thru spamassassin on each restart) I removed the IMAP account from the kmail config. I then switched to thunderbird, created a new IMAP-folder and moved all the mail to it, hoping a fresh index would help.)

After that I fired up kmail again. (It's a day later, so I have an inbox full of spam by this point as I rely on kmail to filter it thru my own rules and then pipe it thru spamassassin.)

I Ctrl-select a bunch of e-mail (about 20) and hit Ctrl-J to filter them (Having previously disabled automating spam-checks by setting the filter items not to run on new mail.)

That works mostly fine, messages are marked as spam (I have to pass them thru the filter again to get the X-Spam-Flay=Y rule to move them to trash, need to figure that out still).

I go for the big kahuna, selecting 1000+ messages and repeat the process, and whilst it looked like filtering was done (I'm tailing the spamd logs amongst other things at this point to check progress) kmail crashed.
