The steps to reproduce are in the ticket linked above, and consists in: - have a choice list for a model field which contains name groups, with the groups' names being translated (using ugettext_lazy) - create a ModelForm for this model - import the ModelForm from an external script that has the settings configured, but not called `django.setup()` yet I understand the steps to reproduce are really a corner case and may seem irrelevant, but this bug means that we might have '''lazy translations that are translated way to early (at import time) instead of staying lazy'''. With the normal Django usage, this will translate too early silently, and not raise any error exception. From what I understand, this happens in the code that checks if the choice (in our case, the name of a group) is the empty choice: https://github.com/django/django/blob/master/django/db/models/fields/__init__.py#L732 I can imagine two solutions to this issue: 1/ only do the check if the ""choice"" isn't a group name 2/ do something like `choice is None or isinstance(choice, six.text_type) and choice == ''` " Bug closed Forms 1.7-rc-1 Release blocker fixed Florian Apolloner Ready for checkin 1 0 0 0 0 0
