23253	"""MANAGERS"" setting doesn't correctly process the value, if it is given as described in the documentation"	angry.kustomer@…	nobody	"Django 1.6.5
According to the docs (https://docs.djangoproject.com/en/1.6/ref/settings/#managers) MANAGERS expects a tuple
of the same format as for ADMINS, that is tuple of tuples.
In the practice it crashes with an error:

    PATH_TO_MY_VIRTUAL_ENV/lib/python3.4/site-packages/django/core/mail/message.py"", line 244, in message
        msg['To'] = self.extra_headers.get('To', ', '.join(self.to))

    TypeError: sequence item 0: expected str instance, tuple found


That is system currently expects it to be a tuple of strings, not other tuples. If given so, everything works fine.
