Changing queryset of Model formsets in __init__ doesn't work

[yofee]

In the ​documentation it says you could change the queryset of a Model formset by setting it in the __init__ method:

class BaseAuthorFormSet(BaseModelFormSet):
    def __init__(self, *args, **kwargs):
        super(BaseAuthorFormSet, self).__init__(*args, **kwargs)
        self.queryset = Author.objects.filter(name__startswith='O')

But in Django 1.5 it doesn't work. It was fixed in some former versions : #17478 (Django 1.3) and #11735 (Django 1.1)

This was fixed in #17478 three months ago (and not backported), that means that this should work in Django 1.6.
