I've tested the checks by disabling the admins for routes and menus. Using MultilangStaticContent without the MenuBundle wouldn't be possible any way because of the hard dependency in https://github.com/symfony-cmf/ContentBundle/blob/master/Document/StaticContent.php#L88

I think if you want to use the MultilangStaticContentAdmin and the MenuBundle is not available you need to implement your own MultilangStaticContent document without the menus property and update the service definitions. Please correct me if i'm wrong.
