KMail crashes when I delete mail in my Inbox (which resides in an IMAP account).
The bug is reproducable, actually, I currently have no way of deleting ANY mail, which is really bad, as I use kmail for my daily work. I attach a backtrace below:

Using host libthread_db library "/lib/tls/libthread_db.so.1".
