virtual folder sidebar provides deceiving new email count

Hi, I stumbled upon mutt-kz, notmuch and afew a couple of months ago and have been fairly happy with how they all work together. One of the quirks I haven't figure out yet, is my sidebar virtual folder new email count. I have a virtual folder Inbox that contains all notmuch query 'to:dzickus@redhat.com'. Going into that folder works great. However, when I leave that folder to go to another virtual folder, it says I have some new messages in my Inbox folder. When I go back into my 'Inbox' folder there is no new messages waiting. Digging through the notmuch database I am _guessing_ the problem is duplicate messages from a mailing list sent to me or cc'd to me. Further guessing is that I am clearing the new flag (by reading the email) in one of the copies but not the other? Querying notmuch produces the same 'unread' count as the virtual folder, so I don't believe mutt-kz is reading anything wrong. So my guess was duplicate files, though I haven't figured out the right notmuch-fu to conclude that properly. Thoughts? Tips? (using mutt-kz::5147a6c1921) Thanks again for the tool! Cheers, Don
