Title:
  Broken compatibility with Django 1.4

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  Horizon is broken on the current master (commit
  a0fc2fd2b4c1057e3c6ba05dca627931b7436108) with Django 1.4.5.

  Steps:
  1. Make sure you use Django 1.4
  2. git pull
  3. python manage.py runserver
  4. browse to http://localhost:8000/

  Expected: the login page is displayed
  Actual: error page saying:
   ImportError at /
  No module named response

  Under Django 1.5.1 the issue disappears.


  The server log:
  --------------------

  $ python manage.py runserver
  Validating models...

  0 errors found
  Django version 1.4.5, using settings 'openstack_dashboard.settings'
  Development server is running at http://127.0.0.1:8000/
  Quit the server with CONTROL-C.
