For Django 1.6: contrib auth password reset confirm view signature changed. The uidb64 parameter was previously base 36 encoded and named uidb36. Had to update urls.py. While I was in there I decided to make the password reset email use the {% url %} tag to be more resilient if the url changes.

urlpatterns = patterns('smiley.views',
    url(r'^farm/$', 'farm', name='smiley-farm'),
    url(r'^farm/extra/$', 'farm', kwargs={'extra': True}, name='smiley-farm_extra'),
