Comment 33 for bug 1360593

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.

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