When you implement facebook logout using FB.logout, make sure its not redirecting before completing the logout action. I have done something like this.

$('#logout-link').click(function(){
        var loc = $(this).attr('href')
        FB.logout(function(response){
                location.href = loc;
        })
        return false;
})

FB Logout says that calling FB.logout will log out the user.

Use <fb:login-button perms='email' autologoutlink='true'></fb:login-button>. And then capture the logout event and simply redirect user to some where you can also logout from your system. When user will click the fb:logout you can capture that event at this function

FB.Event.subscribe("auth.logout", function(response)
 {
  // redirect user to that page where you logout from your system
  });

simple ;-)
