  When trying to retrieve attached private fields, we need to pay attention
  to language handling, possibilities:
   1. Node has no language (locale disabled) and file has no language either
   2. Node has a language but file has no language
   3. Node has a language and file has a language
  For now all attached files are treated the same.
  See http://drupal.org/node/1239916 for examples of arising problems.
