Bug description:
  Hi everybody,

  I'm new to DevStack and during my installation of icehouse devstack, some error arose like this:
  "
  ...
  ls /opt/stack/status/stack/n-novnc.failure
  2014-08-25 07:49:55.739 | + failures=/opt/stack/status/stack/n-novnc.failure

  2014-08-25 07:49:55.741 | + service=n-novnc
  2014-08-25 07:49:55.741 | + echo 'Error: Service n-novnc is not running'

  "

  Then I went to the corrispond screen to check what is wrong:

  "
  cd /opt/stack/nova && /usr/local/bin/nova-novncproxy --config-file /etc/nova/nova.conf --web /opt/stack/noVNC & echo $! >/opt/stack/status/stack/n-novnc.pid; fg || echo "n-novnc failed to start" | tee "/opt/stack/status/stack/n-novnc.failure"
  [1] 2881
  cd /opt/stack/nova && /usr/local/bin/nova-novncproxy --config-file /etc/nova/nova.conf --web /opt/stack/noVNC

  Traceback (most recent call last):

      sys.exit(main())

  TypeError: __init__() got an unexpected keyword argument 'no_parent'
  n-novnc failed to start
  "
  I don't what's going on and how to fix it, anyone have any idea? 
  THX!
