New submission from Guillaume Boudreau:
Tested using urllib3 1.20
```
>>> import urllib3
>>> http = urllib3.PoolManager()
>>> r = http.request('GET',
>>> 'https://online.chasecanada.ca/ChaseCanada_Consumer/Login.do')
>>> r.status
200
>>> r.headers
HTTPHeaderDict({'Date': 'Sat, 04 Feb 2017 20:09:21 GMT'})
>>>
```
I'm pretty sure the problem is caused by an invalid HTTP header returned by the
server:
HTTP/1.1 200 OK
Date: Sat, 04 Feb 2017 19:16:34 GMT
My Param: None
[...]
It directly follows the Date response header, which is returned fine, but since
no other response headers is returned, I think this broken header is breaking
the HTTP response headers parser.
Of note: the `http.client.HTTPresponse.headers` object (`HTTPMessage`) shows
all headers in `_payload`, but only the `Date` header in `_headers`.
Thus why I think this is a http.client issue, and not a urllib3 issue.
