Unicode error with UTF-8 string in next

[nijel]

I'm using Django app and when next URL parameter contains unicode (UTF-8) string, the authentication fails with following exception:

  File "/usr/lib/python2.7/dist-packages/django/core/handlers/base.py", line 114, in get_response
    response = wrapped_callback(request, *callback_args, **callback_kwargs)

  File "/usr/local/lib/python2.7/dist-packages/social/apps/django_app/utils.py", line 45, in wrapper
    return func(request, backend, *args, **kwargs)

  File "/usr/local/lib/python2.7/dist-packages/social/apps/django_app/views.py", line 12, in auth
    return do_auth(request.social_strategy, redirect_name=REDIRECT_FIELD_NAME)

  File "/usr/local/lib/python2.7/dist-packages/social/actions.py", line 20, in do_auth
    redirect_uri)

  File "/usr/local/lib/python2.7/dist-packages/social/utils.py", line 55, in sanitize_redirect
    not isinstance(redirect_to.decode(), six.string_types):

The fix for this was released yesterday, #191 was raised for that. Reopen the ticket if needed.
