In `lib/globalize/active_record/translation.rb`, the `Globalize::ActiveRecord::Translation#locale` accessor casts `locale` as a symbol:

````ruby
def locale
  _locale = read_attribute :locale
  _locale.present? ? _locale.to_sym : _locale
end
````

So I just assumed it was a symbol and treated it as such. No test failures -- is there a case I'm not considering?
