NoReverseMatch on twitter auth with django-socialregistration

I followed the instructions at https://github.com/flashingpumpkin/django-socialregistration to get twitter auth for my little django app.

The only thing I am unsure of is where the urls have to go, so I added to my url patterns.

('^$', include('socialregistration.urls')),

Now, I get:

TemplateSyntaxError at /

Caught NoReverseMatch while rendering: Reverse for 'twitter_redirect' with arguments '()' and keyword arguments '{}' not found.

This is strange as socialregistration.urls does not need any arguments as per https://github.com/flashingpumpkin/django-socialregistration/blob/master/socialregistration/开发者_C百科urls.py

Looks like the twitter_redirect url is only included if you have defined a TWITTER_CONSUMER_KEY in settings.py - have you?
