Не удается подключиться к SMTP-серверу с помощью Django при использовании gevent socket.py

Я запускаю приложение django на gunicorn 0.12.2 с помощью gevent и устанавливаю в среде virtualenv. Когда я пытаюсь подключиться к smtp.gmail.com (представление создания учетной записи django-registration), я получаю следующую ошибку:

Traceback:
