Description of problem:
I've updated to fedora 22 recently and python(3)-bugzilla stopped working. It seems that due to some change lower in the stack (python?) python-bugzilla now tries to accept gzip encoded replies but doesn't handle them at all.

Version-Release number of selected component (if applicable):
python-bugzilla-1.2.0-1.fc22.noarch
python3-bugzilla-1.2.0-1.fc22.noarch

How reproducible:
Run this script using both python and python3:

from bugzilla import RHBugzilla4
bz = RHBugzilla4(url="https://bugzilla.redhat.com/xmlrpc.cgi")


Actual results:
Traceback (most recent call last):
  File "/usr/lib/python3.4/site-packages/bugzilla/base.py", line 237, in _request_helper
    return self.parse_response(response)
  File "/usr/lib/python3.4/site-packages/bugzilla/base.py", line 210, in parse_response
    parser.feed(response.text.encode('utf-8'))
  File "/usr/lib64/python3.4/xmlrpc/client.py", line 445, in feed
    self._parser.Parse(data, 0)
xml.parsers.expat.ExpatError: not well-formed (invalid token): line 1, column 0

During handling of the above exception, another exception occurred:

    self._parser.Parse(data, 0)
bugzilla.base.BugzillaError: not well-formed (invalid token): line 1, column 0


Expected results:
Nothing, it should just work.

Additional info:
When a debugger is attached, I can see binary response getting from bugzilla.
