I've extracted Lorn's connectivity-api draft commit and made it self-
compiling:

https://code.launchpad.net/~timo-jyrinki/+junk/connectivity-api-bearer

You can either compile it yourself on the device or get this build for
vivid/rc-proposed: https://launchpad.net/~ci-train-ppa-
service/+archive/ubuntu/landing-059/+build/8313308/+files/libqt5network5-connectivityapibearer_0.0.1
%7Eunreleased-0ubuntu1%7Evivid1%7Etest1_armhf.deb

It seems not to crash at least on device, but I don't know how to test it further. To test it:
1. Install the .deb
2. Remove/move the three other bearers from /usr/lib/arm-linux-gnueabihf/qt5/plugins/bearer away so that only libqubuntubearer.so is left
3. Reboot

There'd now be also the new upstream method of
QT_EXCLUDE_GENERIC_BEARER=1 that will be in Ubuntu's Qt 5.5 packages,
but then I do not how it would be selected if NM or Ubuntu backend is
used - if we get connectivity-api bearer working well enough, we should
be able to specify it explicitly.

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
