Checking permissions in report3 SLA Services

I'm get error about not permissions, when clicking to field "SLA (Last 7 days)" for service without triggers (general service).

in report3.php:
if (!is_null($service['triggerid'])) {
$options = array(
'triggerids' => $service['triggerid'],
'output' => API_OUTPUT_SHORTEN,
'nodeids' => get_current_nodeid(true)
);

$db_data = API::Trigger()->get($options);
if (empty($db_data))

{ access_deny(); <- this }

}

php check returned information about triggers, but i don't have trigger for some Services SLA
