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
