      Description

      This bug was tracked at:
      https://bugs.launchpad.net/unity8/+bug/1480877
      and has to do with the network-manager bearer plugin.

      "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"
