Comment 17 for bug 883459

Running Gentoo stable, just pulled in kmail2. my pop account is showing multiple copies of messages that have been moved to another folder by a filter rule. Also, when I click on the Inbox messages that had been moved by filter suddenly appear in the inbox, then are moved back into the the folder specified by the filter rule (and thus the duplicate).
Also checking email will cause the filtered messages to duplicate.
This is not happening with my IMAP accounts (though none of my filters affect messages that typically come in through the accounts I access via IMAP).

Happy hunting.
