Notice: Undefined index: in /var/www/wp-admin/includes/menu.php on line 219

When a new role is created with no capabilities that allow the user to view the back end like so ( added to end of functions.php for twentyeleven theme. ):

add_action( 'init', 'add_new_roles' );
function add_new_roles(){
    add_role( 'new_role', 'New Role', array( 'read', 'foo' ) );
}

create a new user with the 'new role' and then log out and log back in as this user. with WP_DEBUG set to true it shows the message saying you do not have permissions to view the page but then there's a notice above it saying Notice: Undefined index: in /var/www/wp-admin/includes/menu.php on line 219.

I just did a new svn checkout and tried it with the twentyeleven theme to be sure it wasn't something that I did and it still did it.
