[Pkg-mailman-hackers] Bug#971084: /usr/share/mailman3-web/manage.py mmclient does not observe $PYTHONSTARTUP

[monochromec]

Package: mailman3-web
Version: 0+20180916-8
Severity: normal
Tags: a11y

Upstream patch @ https://gitlab.com/mailman/mailman/-/issues/469 seems to be in
place but invoking mmclient as described still fails to observe
$PYTHONSTARTUP environment variable.

Happy to provide additional information - just let me know.
