I keep getting ""'AuthQuerySet' object has no attribute '_known_related_objects'"" when trying to invoke methods on a class that uses the queryset. I've confirmed that I do not get the error in b2 but do get the error in rc1 - so I'm comfortable stating that something changed for the worse between b2 and rc1. I'm really sorry this is so vague, but I don't understand the error message, and I don't know what code to post. I'd be happy to chat with someone on IRC about it though, and I can run any tests suggested. Perhaps it's related to https://github.com/django/django/pull/617 ?",Bug,closed,Uncategorized,1.5-beta-1,Normal,invalid,,,Unreviewed,0,0,0,0,0,0
