Hi I updated my builds and am facing the following error : InvalidTemplateLibrary: Invalid template library specified. ImportError raised when trying to load 'postorius.templatetags.membership_helpers': cannot import name MailingList I tried building on my other machine and faced the same error. Complete traceback : http://dpaste.com/3WG8XQ5 Thanks Anirudh (irc spark) I guess it's caused by an out of date mailmanclient installation inside one of your virtualenvs. Can you try clearing them out?

The issue is caused by the following import: from mailmanclient._client import MailingList

This import should not be there. We should not import via "private" things. Currently the MailingList is imported for additional functionality, but it's not actually being used inside Postorius. I guess a safer option would be to use postorius.models.List instead. We should be using these classes inside Postorius anyway.
