    Fix a fatal "_content_is_empty" error in some case.
    
    Using CCK3, and not choosing to hide the "other" fields when having
    a multivalue field in the content type leads to fatal error when
    trying to validate the form: content_validate tries to find
    informations about the fields in $form['#field_info'], but $form
    was empty.
