Bug 280729

Application: kmail (1.13.6)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- Background
I am setting up kmail on a new machine. I copied some filter files from my old kmail on my old machine. I finished setting up accounts, appearance, etc. I copied all the mail content from my old kmail to the new kmail. I've started and exited kmail a couple of times.

- What I was doing when the application crashed:
setting expiry on folders
I set expiry on trash (read=30, unread 14). That went fine.
I set expiry on zRjct read=90, unread=120. When I clicked "ok" (or something), kmail died instantly.

- Unusual behavior I noticed:
I could not run kmail from the system bar (it would blink a few times, then nothing came up). I was running it in from a terminal. It has been spewing all manner of warnings and errors during regular operation. Here are the last few in the terminal window:
