[Pkg-mailman-hackers] Bug#1028994: mailman3: (autopkgtest) needs update for Python 3.11

[Graham Inggs]

Source: mailman3
Version: 3.3.7-3
Severity: serious
User: debian-ci at lists.debian.org
Usertags: needs-update
User: debian-python at lists.debian.org
Usertags: python3.11
Control: affects -1 src:python3-defaults

Hi Maintainer

The autopkgtests of mailman3 fail with Python 3.11 as the default
version (and Python 3.10 still supported).  I've copied what I hope is
the relevant part of the log below.

Regards
Graham
