@Lorn

Thanks for the update.

I usually do all my testing on rc-proposed, as it's latest and greatest.
I wasn't aware of the "ubuntu-developer" channel.  I've tested on rc-
proposed/bq-aquaris.en ( #188 ) with the full set of packages from
silo-026, and everything seemed good to me.

Thar said, I've reviewed your latest changes and they look good to me.
Not creating QNetworkManagerInterfaceDevice and DeviceWireless instances
definitely gets rid of the a bunch more DBus signal match rules, and
unneeded DBus calls.  DeviceWireless is still generates
PropertiesChanged signals every time a scan finishes...

With this code removed, the plugin operates soley on active and system
connection updates.

Regarding the device adds for 'rmnet' devices on mako, in theory these
should've only been happening at start-up time and/or whenever flight-
mode is turned off.

Anyways, I'm +1 for including your latest revision of the patch.
Thanks again for your help!

Bug description:
  Krillin, rc-proposed, r83

  
  DESCRIPTION:
  I've been trying to track down the cause of the occasional UI freezes on my Krillin device, and I noticed that whenever the UI freezes for 2-4 seconds, I get a burst of "PropertiesChanged" signals in dbus-monitor

  Here's a log of what's shown in dbus-monitor:
  http://pastebin.ubuntu.com/11992322/

  I'd guess the problem is in the code that actually catches the signals
  and acts accordingly.

  HOW TO REPRODUCE: 
  1) Move to a place where many wifi hotspots are available
  2) Connect the device via USB and run "phablet-shell" and then "dbus-monitor"
  3) Use the device while keeping an eye on dbus-monitor output
