Authenication window occasionally fails to open, then affects all policykit instances

[Doug McMahon]

Unfortunately this seems to happen 'out of the blue', then only a log out in returns to working (other than authenticating thru a terminal like in pkexec synaptic which will work

Ex. errors -
synaptic -
 Error creating textual authentication agent: Error opening current controlling terminal for the process (`/dev/tty'): No such device or address

Software-center when trying to install a package -
 softwarecenter.backend - WARNING - _on_trans_error: org.freedesktop.PolicyKit.Error.Failed: ('system-bus-name', {'name': ':1.370'}): org.debian.apt.install-or-remove-packages

software sources when trying to change server -
dbus.exceptions.DBusException: com.ubuntu.SoftwareProperties.PermissionDeniedByPolicy: com.ubuntu.softwareproperties.applychanges

user-accounts when trying to unlock -
(gnome-control-center:8358): Gtk-WARNING **: Error acquiring permission: Failed to acquire permission for action-id org.freedesktop.accounts.user-administration
