A subscriber to a mailing list I administer has been sending 8bit UTF-8 encoded mail, with no further quoted-printable / base64 / etc. encoding.
Based on the symptoms, I'm guessing this means the SMTPUTF8 extension. Mailman is not prepared for this as far as I know. That is, Mailman expects that the headers will be ASCII, possibly MIME-encoded.
I'm guessing the problem is that either the host MTA or Mailman's LMTP server doesn't handle SMTPUTF8 negotiation correctly, but I do not have time to analyze for some days.

Your message doesn't have UTF-8 in the *header* as far as I can see.
