[Mailman-Developers] Facing build Issues Postorius

[Anirudh Dahiya]

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
