Cannot turn on location: it switches back to off by itself

[Alberto Mardegan]

Location was not working on my newly acquired Meizu pro 5.

I went to system-settings -> Security & Privacy -> Location and switched on the GPS. But then, when navigating back to the Security & Privacy page, the location was shown as off (and indeed, there was no location icon in the indicator).
I've repeated it several times, also exiting from the system-settings to make sure it was not a problem in the client, but that didn't help: the settings was always being reset to "off".

I also run "dbus-monitor --session" on the terminal and I could see that there was some activity around the location (see the attachment).

I eventually stopped the ubuntu-location-service service and restarted it, and things started working.
