8011	Translated strings in a ForeignKey of a model in an application not in the project root causes errors	anonymous	Malcolm Tredinnick	"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:

(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."		closed	Translations	dev		fixed	translation, lazy, model	oliver@…	Accepted	0	0	0	0	0	0
