There was a bug in the branch heads cache. There is no bug report for
it, but it's in NEWS:

        - In 0.46 and 0.47, monotone could sometimes get confused
          about which revisions were the heads of a particular branch.
          This would happen when a new branch cert was added to a
          revision that was an ancestor of one or more of the current
          heads of the branch, most commonly during netsync when
          multiple people had performed identical merges. This is
          fixed now. 'db check' will identify the problem; if your
          database currently gives incorrect 'heads' results, or 'mtn
          bug' on 'merge', you can fix it by running 'mtn db
          regenerate_caches'.
