[Bug 874757] [NEW] Cannot toggle additional sources until authentication has been granted through other means

[Dylan McCall]

Public bug reported:

Steps to reproduce:
1. Open Software Sources as an admin user (not as root; don't do this through Synaptic).
2. Try to check or uncheck the Cdrom source or a source in the Other Software section. Nothing will happen.
3. Do another action that triggers a PolicyKit authentication dialog (toggle the multiverse or universe source, or add a source in Other Software)
4. Repeat step 3. This time, the source will be toggled appropriately.

In step 2, the following lands in stderr:
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 647, in on_isv_source_toggled
    self.backend.ToggleSourceUse(str(source_entry))
  File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 143, in __call__
    **keywords)
  File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 630, in call_blocking
    message, timeout)
dbus.exceptions.DBusException: com.ubuntu.SoftwareProperties.PermissionDeniedByPolicy: com.ubuntu.softwareproperties.applychanges

Attempting to toggle a software source in the Other Software section
should trigger an authentication dialog.
