NoneType error upon authenticating user (Facebook)

[geekscrapy]

The following error is reported when I have a user authenticate that has already been created. I've only tested this on Facebook.

django.get_version() = '1.9.8'

It looks like it's not getting/creating a user upon return from Facebook.

If I change:

LOGIN_URL = 'account:login' to LOGIN_URL = '/account/login/'

It doesn't error, but sends me to the login page.

FYI, i'm also using the ?next param to send the user back to the same page at which they are authing

Can't debug without a proper traceback and the data involved. Closing, please reopen in social-app-django if still relevant.
