Crash when loading invalid or unreadable location details (indicator-weather crashed with AttributeError in on_city_changed(): 'indicator_weather' object has no attribute 'current_location')

Crash when updated to the 6/22 release from the previous one.

Deleted all location data (probably of the old-format) and it no longer crashes.
