Check out [this comment](https://github.com/refinery/refinerycms/blob/master/pages/app/models/refinery/page.rb#L129-L132) for `in_menu` method (which is used while constructing menu):

> Shows all pages with :show_in_menu set to true, but it also
> rejects any page that has not been translated to the current locale.

I also did a quick test and I only get menu items which are indeed translated... Am I missing something?
