So between comments 29 and 31, it *looks* like the in-process location-
service proxy for scopes provided by unity-scopes-shell is making a
synchronous request to the location service.  This causes the dash to
"freeze" waiting for the dbus call to time out.

While this happens, because communication between the dash and the
unity8 shell are also synchronous, we end up freezing unity8 too.

There are fixes in flight for both, although only the first issue needs
to be fixed to consider this bug fixed.

https://code.launchpad.net/~mzanetti/unity8/async-dashcommunicator/+merge/235272

*Hopefully* once that first branch lands (it's in silo now), we can see
if this is reproducable still.

Title:
  unity8 freezes randomly

Status in “unity8” package in Ubuntu:
  Confirmed

Bug description:
  krillin #205

  [Sorry for the poor description]

  On krillin UI freeze randomly. For example on the screenshot it
  occurred while dragging the greeter to unlock the phone. I was playing
  music, woke up the phone with the power button to turn the display on
  and did a right edge swipe to remove the greeter.

  This has been reported by several people in the past days, but I
  didn't find a pattern to reproduce this bug reliably.

  There is no crash in /var/crash and no apport activity.
  If I press the power button to turn the screen off/on again, the greeter is completely displayed (ie. doesn't cover half of the screen like the screenshot) but the UI is not responsive to gestures or input events. A long press on the power button shows the shutdown dialog but none of the button can be pressed.

  top doesn't show any specific process going crazy
