21559	Can no longer query reverse generic relations in Django 1.6	khoobks@…	nobody	"Please see the code below for a demonstration of the regression.

== The Model ==

class TaggedItem(models.Model):
    tag = models.SlugField()

    def __unicode__(self):
        return self.tag

class Bookmark(models.Model):
    url = models.URLField()
    tags = generic.GenericRelation(TaggedItem)

== The Setup ==
{{{
from test_app.models import *

b = Bookmark(url='https://www.djangoproject.com/')
b.save()
t1 = TaggedItem(content_object=b, tag='django')
t1.save()
t2 = TaggedItem(content_object=b, tag='python')
