Description of problem: If you move a message that matches a filter from a folder to the INBOX (using IMAP here) the message is immediately re-filtered again and sent to the folder target of the filter. This is ok for new messages but shouldn't happen for messages that are marked as read and that I myself am dragging back to INBOX.
This is because of my change in GNOME bug http://bugzilla.gnome.org/show_bug.cgi?id=324804 thus moving this upstream as http://bugzilla.gnome.org/show_bug.cgi?id=534938 Thanks for reporting this.
