 Using Python 2.7.6 and Django 1.7.6 we got an internal server error when
 there were ''Referer'' and non-ASCII ''User-Agent'' headers on a request
 that lead to a 404 response:
 {{{
 Traceback (most recent call last):
   File ".../django/core/handlers/base.py", line 204, in get_response
     response = middleware_method(request, response)
   File ".../django/middleware/common.py", line 156, in process_response
     "IP address: %s\n" % (referer, path, ua, ip),
 UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 0:
 ordinal not in range(128)
 }}}

 This is a problem goes back to at least
 
[https://github.com/django/django/blob/stable/1.4.x/django/middleware/common.py#L103
 1.4.x] and is still a on
 
[https://github.com/django/django/blob/stable/1.8.x/django/middleware/common.py#L144
 1.8.x].

 I have a fix with a test that I will create a pull request for.
