I am using kmail embedded in kontact with POP (gmail) and Disconnected IMAP (Exchange 2003) accounts. I was working on Inbox of my IMAP accounts, moving e-mails to some folders and removing some e-mail (moved to trash), then emptying the trash.

Since I use manual mail check, I had performed Manual check of my Disconnected IMAP account, which resulted in crash with the following stack trace:

It seems that the problem is reproducible.
