I'll try to address some questions here, more answers will come in the
next comment, sorry about that.

It seems to always happen at least at the office (BlueFin), where your
script reports 26 APs.

Yes the problem disappears if I disable WiFi.

After reboot, the problem disappears, at least at the beginning, the
number of PropertiesChanged I see in dbus-monitor is much lower. So it
seems to be about something which gets worse with time. Even if I didn't
move, I'm seeing 1-4 PropertiesChanged at a time instead of 30-ish.

I've been waiting for 10minutes but I still don't have the problem,
after reboot.

I'll try disabling the dbus bridge as soon as I get the problem again,
which is just a matter of time I guess.

The eduroam is most likely not related.

Yes I have the latest update installed, r94 rc-proposed, krillin.

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

Status in indicator-network package in Ubuntu:
  Incomplete
Status in network-manager package in Ubuntu:
  Incomplete

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
