Translated strings in a ForeignKey of a model in an application not in the project root causes errors

[anonymous]

This seems like a real edge-case, but still it is an issue (for me at least). Since the memory optimization stuff from [8127], if I have a lazily translated string (in this case as the verbose_name) for a ForeignKey, which is in a model located in an application not in the project root (in this case in project.generic.tagging, I get this lovely error:

AttributeError: 'module' object has no attribute 'tagging'

(This actually happened in django-tagging). I've tracked it down to changes made to or in django.utils.functional.lazy.__proxy__.__promise__.__wrapper__ — it doesn't appear that it got called prior to these changes (in [8119] at least), if that helps at all.
