IP Address not displayed for wifi access points

[Bill Filler]

latest rc-proposed build 319

Open system settings
expand the connected access point by pressing right arrow

expected results:
ip address is displayed

actual results:
ip address is not displayed, just a label "IP Address" with no value

I see this on mako running stable / #30 plus the a test version of NetworkManager 1.1.93 that I'm using for the VPN bug #1579222. When I go to the access point details page in system settings, I also see the following message logged to the upstart log file application-legacy-ubuntu-system-settings.log:

2016-05-09 12:36:50,542 - WARNING - Got invalid serialized mime data. Ignoring it.

When I go back to the main WiFi settings page, I also alot of the following log messages:

2016-05-09 12:34:24,080 - WARNING - file:///usr/share/ubuntu/settings/system/qml-plugins/wifi/PageComponent.qml:80: TypeError: Cannot read property of null

This is in the log for uss when trying to expand the AP on the UI.

That log entry [1] is not related to the WiFi panel. I think it's copy/paste something complaining.

[1] WARNING - Got invalid serialized mime data. Ignoring it.

On my turbo the Ip4Address = 0. On my desktop it's not 0, sounds like a bug in network-manager to me.

      interface org.freedesktop.NetworkManager.Device {
        methods:
          Reapply(in a{sa{sv}} connection,
                  in t version_id,

          GetAppliedConnection(in u flags,

                               out t version_id);
          Disconnect();
          Delete();

@Ken

I see the same thing on krillin running rc-proposed / #320.

That said, looks like we made a poor choice of properties to use as 'IP4Address' was marked as deprecated as far back as NM 0.9:

https://developer.gnome.org/NetworkManager/0.9/spec.html#org.freedesktop.NetworkManager.Device

Looks that choice has now bitten us, and the property is no longer being populated on purpose.

indicator-network is not involved in reading the IP address of connections.
