Location instance has no attribute 'location_code'

[Alexey Kotlyarov]

When adding East Melbourne as a location, "Apply" buttons seemingly does nothing; there is an AttributeError in the console output.

How to reproduce:
1. Go to Preferences, Locations, select Add.
2. Search for "East Melbourne".
3. Select "East Melbourne, Victoria, Australia", select Next.
4. Enter any name for it, select Next.
5. Select Apply.

Expected results:
East Melbourne is added as a location.

Actual results:
Nothing happens when Apply button is pressed. In the console, the following output is produced:

Traceback (most recent call last):
  File "/usr/bin/indicator-weather", line 1882, in on_apply
    (location_code, location_details) = self.location.export_location_details()
  File "/usr/bin/indicator-weather", line 405, in export_location_details
    return (self.location_code, self.location_details)
AttributeError: Location instance has no attribute 'location_code'

Still occurs in 12.04.5 which contains the patch from Bug #821233 so it can not be a duplicate of that issue.
