django-pipeline crashes python social auth

Currently I'm working in a little project that is contemplating social authentication (so python-social-auth is great). Also, I wanna to integrate django-pipeline to handle my assets (css principally).

JS to perform a social sign up:

vm.doSocialAuth = function(provider) {
  var authURL = '/auth/login/' + provider + '/?next=/auth/completed/';
  $window.open(authURL, 500, 500);
};

Social authentication works fine.

But when I do:

INSTALLED_APPS += ['pipeline']
PIPELINE = {
    # 'PIPELINE_ENABLED': True,  # Missing this allows pipeline in debug mode
    'STYLESHEETS': {
        'main': {
            'source_filenames': (
              'css/cover.css',
            ),
            'output_filename': 'css/main.css',
            'extra_context': {
                'media': 'screen,projection',
            },
        },
    },
}

And I try to make a social sign in, this exception is triggered:

I don't know if its a issue for python-social-auth library or for django-pipeline, so I've posted it here.

Any help is appreciated.

The credit for the next answer is all for Julian Bez, he posted this comment.

And he is basically suggesting to define a SOCIAL_AUTH_PIPELINE variable inside our project's settings file and python-social-auth is going to work smoothly with django-pipeline.

So, here's my SOCIAL_AUTH_PIPELINE:

settings.py

# By defining SOCIAL_AUTH_PIPELINE, we avoid a conflict between django-pipeline
# and python-social-auth.
SOCIAL_AUTH_PIPELINE = (
    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',

    # Send a validation email to the user to verify its email address.
    # Disabled by default.
    # 'social.pipeline.mail.mail_validation',

    # Associates the current social details with another user account with
    # a similar email address. Disabled by default.
    # 'social.pipeline.social_auth.associate_by_email',

    'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details',
)
