Debug Notice about check_admin_referer when debug enabled

FYI: When I save the options I got this:

Notice: check_admin_referer was called incorrectly. You should specify a nonce action to be verified by using the first parameter. Please see Debugging in WordPress for more information. (This message was added in version 3.2.) in /wp-includes/functions.php on line 3245

When Force Invisibility was not checked there was an additional message about sc_invisible not being set.

WP_DEBUG was set to true.
