[e-lang] [Meta] duplicate messages (was Re: [cap-talk] ...)

[Message sent to both cap-talk and e-lang]

I received two copies of this, one with subject starting
"Re: [cap-talk] [e-lang]", and the other with subject starting
"Re: [e-lang] [cap-talk]", but with the same Message-ID.
(Same for Ihab's reply.)

I'm sure that never used to happen. Both lists are hosted by Mailman
at mail.eros-os.org, and I thought that the default behaviour of
Mailman was to suppress duplicates (or maybe something else was
suppressing duplicate Message-IDs).

I recently changed my subscription address, but I did that globally
for all mail.eros-os.org lists, and only between two different aliases
for the same Google Mail account. The Envelope-to field shows my new
address (david-sarah at jacaranda.org) on both messages. Is anyone else
seeing duplicates?
