It's not a bug, it's a misfeature. Articles that are gated from
the mailing list to the newsgroup have improperly truncated
reference lists, so newsreaders can't put them together properly.

If you look at the headers for a message posted via news, you'll
find something like:

References: <mailman.1063135996.15871.python-list at python.org>
<3F5ECDE2.40206 at mxm.dk> <3F5ECEF7.9080409 at mxm.dk>

However, if you look at the headers for a message gated
from the Python mailing list, you'll find:

References: <mailman.1063135996.15871.python-list at python.org>

Which happens to be the ID of the first message in the tree, (which was,
coincidentally, gated from the mailing list.) regardless of how far down
in the tree it happens to be.

Then if, for some reason, you don't have the message at the top
of the tree, you get this scatter effect.

I have no idea whether this is a problem with Mailman, the
Mail RFCs, or the mail to news gateway.
