Description (Last modified by mtredinnick)

smart_unicode and force_unciode throw TypeError exception when calling on instance of AnonymousUser. I got this error when trying something like this ( for model Articles.authors = ManyToManyField(User) ): 

from django.contrib.auth import AnonyousUser
auser = AnonymousUser()
Article.objects.filter( authors__in = [auser] )

Then i got: 

TypeError: coercing to Unicode: need string or buffer, __proxy__ found

Full trackback is in attachment.

True. This is kind of obvious in retrospect. The __unicode__ method must return a unicode object, not anything else, so we cannot return lazy translation objects from those methods. Easy enough to fix; painful to track down if we're making the same error anywhere else, though.

(In [5421]) unicode: Fixed #4472 -- Must return unicode objects from unicode methods. Lazy translation proxies are not an acceptable substitute.
