OK, I understand the problem now. Although I don't understand how it's
possible. Can you please do the following test:

- go on a mail, try <F9> on it to ensure it exhibit the bad behavior
  you've reported

- find out the Message-Id of that mail, e.g. "20130213095752.GA20009@foobar"
  ('h' will show all the headers of the mail in Mutt, in case you're not
  seeing the Message-Id header by default)

- on a shell prompt, try:

    notmuch search --output=threads id:20130213095752.GA20009@foobar

  with the appropriate message id for your case, preceded by "id:"

- it should give you something like

  thread:0000000000018bce

That's correct (as long as the archived messages are still part of
notmuch index), and it's working for quite a lot of people, hence I'm
eager to find out what's not working in your setup.

Cheers.
