Well, first of in debugging it I've found the following things:

1) it only appears if there is in fact new mail in the folder
   (otherwise gnus-agent-braid-nov doesn't even get called).

2) the problem comes from the fact that the if statement which decides
   whether to insert the contents of the old .overview file into the
   nntp buffer bases it's decision on the last article number in
   the list of articles and the .overview file.  If the list of
   articles contains anything newer, then the *entire* contents of the
   .overview file is inserted.  I think this is where the duplication
   is going on.
