Title:
  Exception in GTK frontend when attempting to connect to wifi

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  The following exception occurred when 'Connect' button was clicked
  after entering the wireless password on 'Wireless' screen on a non-
  live session installation using saucy desktop with 20130510 image.

  Exception in GTK frontend (invoking crash handler):
  Traceback (most recent call last):
    File "/usr/lib/ubiquity/ubiquity/frontend/gtk_ui.py", line 1435, in on_next_clicked
      if ui.plugin_on_next_clicked():

      message, timeout)
  dbus.exceptions.DBusException: org.freedesktop.DBus.GLib.UnmappedError.NmManagerError.Code4: Not authorized to control networking.

  The steps to reproduce:
  1. Boot the hardware with a saucy installation usb 
  2. Press any key when human-keyboard screen appears
  3. Leave the default 'English' language selection and click continue (any attempt to connect to wifi networks at this stage would fail with 'Not authorized to control networking' message)
  4. Click 'Continue' on the 'Preparing to install Ubuntu' screen (here the connection status to the internet would not be ticked)
  5. Now on the 'Wireless' screen, Enter the password for the known wifi network and click 'Connect'
  6. The crash could be observed at this point.
