Package: python-urllib3
Version: 1.11-1

This version of the package fails to work when python-future is installed.

The start of urllib3/util/response.py looks like:
try:
import http.client as httplib
except ImportError:
import httplib
The try is expected to fail on Python 2.7, but it succeeds because
python-future includes /usr/lib/python2.7/dist-packages/http/client.py which
looks like this:
from __future__ import absolute_import
import sys
assert sys.version_info[0] < 3
from httplib import *
