County field won't save in profile create mode

I first thought this might have to do with my monkeying around with county stuff, but I've re-created the problem on the demo site.

If you have a profile with a county field, and use it in create mode, the county input isn't saved.

It turns out that in CRM_Contact_BAO_Contact::createProfileContact(), the county information was saved in $data['address'][$loc]['address']['county_id'] instead of $data['address'][$loc]['county_id'] like all the other address fields. I've attached a patch with the single line change.
