This is because people are using reply-to-all, instead of
reply-to-list or reply-to. I can resolve this by discarding duplicate
message ids, but thats more of a sledgehammer. Far better would be for
people to stop being silly and using reply-to-all, and instead use
reply-to-list or reply-to, both of which are set properly and behave
correctly.

Debbugs has nothing to do with these message IDs; it adds
Resent-Message-Id: for the messages which it forwards, and retains the
original Message-Id:. Most likely this is something to do with the
mailman list-to-news gateway.
