Test fixtures break postgresql_psycopg2 backend

I get the following error:

Traceback (most recent call last):

  File "/usr/local/lib/python2.5/site-packages/django/core/handlers/base.py", line 68, in get_response
    callback, callback_args, callback_kwargs = resolver.resolve(request.path)

ViewDoesNotExist: Tried list in module intranet.orders.views.vpn_review. Error was: 'psycopg2._psycopg.cursor' object has no attribute 'dictfetchone'

It started to work for me with this simple patch

Already fixed in [4660].
