Public bug reported:
Hi,
When mailing list is configured with:
preferred_language = 'ja'
available_languages = ['en', 'ja']
send_goodbye_msg = 0
And mailman receives confirmation email for unsubscription with multipart
message encoded in
different encoding than euc-jp, then mailmans command runner crashes with
traceback:
Feb 10 18:08:00 2021 (1270) Uncaught runner exception: 'euc_jp' codec can't
decode bytes in position 280-281: illegal multibyte sequence

Here is an example of a mail which triggers this:
Date: Wed, 11 Nov 2020 14:13:16 +0900
Subject: Re: ###CONFIRM###
From: <testuser2@###SERVER###>
To: userlist-request@###SERVER###.com
MIME-Version: 1.0
Content-Type: multipart/alternative; boundary="000000000000663b1c05b3cdda78"
--000000000000663b1c05b3cdda78
Content-Type: text/plain; charset="UTF-8"
Content-Transfer-Encoding: base64
44GT44KT44Gr44Gh44Gv5LiW55WM
--000000000000663b1c05b3cdda78
Also its maybe worth pointing out that setting RESPONSE_INCLUDE_LEVEL to <=1
mitigates this.
I've managed to fix this issue by decoding the message part with its original
charset and then encoding it to preferred encoding of mailing list.
I'm attaching my patch. Could you please consider merging it?
Thanks for any help you can provide.
