Re: the xenial version of dbus, you need to be careful as although I was
able to get it to run on a krillin, it prevented the UI from coming up
on mako.   This is why I backported the changes and pushed to my PPA (
1.8.12-1ubuntu5~awe3 ).

I'd appreciate if you could test too.   Note, to be able to verify the
current number of match rules, you'd need to install dbus from my PPA.
Your other choice is stopping the three location service jobs per
comment #56, although this obviously will cause you to lose location
services for the duration of your testing.  Unfortunately, there's no
way around this.

Title:
  Access points' "PropertiesChanged" dbus signals freeze UI on mobile
  devices

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
