threading broken in g.e.gnus (was: Can't send emails to this list via gmane?)

[Tim Howe]

I'm noticing many of the threads in here are completely broken.  It
seems the Message-IDs are getting replaced by Mailman ones so References
and In-Reply-To headers are left dangling.  So Gnus falls back to the
"same-subject-guessing" behavior.

Is this intentional?

You can try customizing `gnus-summary-thread-gathering-function'.
Gnus's default is indeed to fall back on Subject if References are
wrong, but you can eliminate this behavior if you wish.  See also (info
"(gnus) Loose Threads").

Thanks for that, but I was actually commenting on the munging itself,
not how Gnus is handling it on display.  It seems something (GMANE?) is
chewing on the articles and replacing the Message-IDs with "Mailman"
ones, meaning that references and threading are broken non-predictably
depending on the path messages take.

Yes, the problem seems correlated to [followups to] posts made from
info-gnus-english-mXXj517/zsQ@public.gmane.org, as opposed to the Gmane or Google Groups
routes.  It's still noticeable, although not as frequently, with my
display settings for Gnus ( http://ompldr.org/vaHo3dQ ).

Crossposting to gmane.discuss to see if the Gmane admins have an idea
about this.

Best,
Will
