anonymous user cannot be converted to string

[canburak@…]

the code:

class SomeMiddleware:
    def process_request(self, req):
        print type(req.user)
        print type(req.user.__str__())
        print req.user.__str__().__class__
        print req.user
        return None

prints out

<class 'django.contrib.auth.models.AnonymousUser'>
<type 'instance'>
django.utils.functional.__proxy__
Traceback (most recent call last):

(Fixed description formatting.)

I thought we'd fixed this. Apparently I am confused, though, and it is only fixed on the Unicode branch.
