nmcli - inconsistent response to query......

[Another Sillyname <anothersname googlemail com>]

Hi

I have a monitoring script that I wrote back end of last year to
monitor the status of a TUN as gnome was not reporting when the TUN
failed.

As the problem didn't get resolved last year I waited till Fedora 22
shipped with NM 1.x to revisit the problem.

Withing the script there's a monitoring section that relies upon the output from

> nmcli c show --active

to give me the current status of the connections, however under F22 I
am now occasionally seeing the error....

(process:YYYYYY: nmcli-CRITICAL **: Error: Could not create NMClient
object: Permissions request failed: Authorization check failed:
GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message did not
receive a reply (timeout by message bus).

Instead of the expected........

NAME             UUID
  TYPE                  DEVICE
tun0                UUID blanked out for obvious reasons     generic
              tun0
AVPN-TCP80  UUID blanked out for obvious reasons      vpn
       enp9s0
LAN                UUID blanked out for obvious reasons
802-3-ethernet      enp9s0

This unexpected error message is playing havoc with the parsing in my
script and as it doesn't happen under Fed21 I wonder what's
changed......is there any way nmcli could handle a timeout error a bit
more eloquently?
