Python backtrace from `mailman -h`
Hi Folks,
I'm running the Debian-packaged mailman3 (yes I know ...)
and running:
sudo -u list mailman -h
gives a python backtrace (which I've appended the tail end of).
Can someone who has the upstream installed version (using venv)
please check that mailman -h works there before I waste too much time
investigating in the wrong places?

Yes, mailman -h works and produces the same help output and list of
subcommands as mailman with no arguments or options. Does it work with
no options? Does it work if you do mailman -C path/to/mailman.cfg -h?

Thanks. Without options it works; and it works with an explicit config path. So I know where to look to fix it (and will report it on the Debian bug tracker)
Interestingly: sudo -u list mailman -C /etc/mailman3/mailman.cfg -h works, but sudo -u list env MAILMAN_CONFIG_FILE=/etc/mailman3/mailman.cfg mailman -h does not.
And sudo -u list mailman info reports /etc/mailman3/mailman.cfg as the current configuration file.
