I'm a bit confused, but I think I understand. You say this is Mailman
2.1.9, but the above traceback says
/usr/lib/mailman/Mailman/Gui/Privacy.py defines a list attribute
dmarc_quarantine_moderation_action which didn't exist before 2.1.18.

My best guess is something backported the DMARC mitigations into your
Mailman 2.1.9 and also included code in Mailman/versions.py to update
older lists, but whether or not a list gets updated by this process
depends on the list's data_version being less than the DATA_FILE_VERSION
defined in Mailman/Version.py.

So, still guessing but, the backport incremented DATA_FILE_VERSION so
all the existing lists got updated except the list that came from the
2.1.14 Mailman that already had a data_version >= the new DATA_FILE_VERSION.

To fix this, do the following:

bin/withlist -l problem_list_name
(responses from withlist ending with prompt)
>>> m.data_version = 1
>>> m.Save()
>>>            <- control-D here to exit

If I am correct, that will fix the problem, and If it is something else,
no harm will be done.
