Bad watchdog call when deleting a key

In services_keyauth.admin.inc, the services_keyauth_admin_keys_delete_confirm_submit function, the call on watchdog is:

watchdog('menu', 'Deleted key %key.', array('%key' => $t_args), WATCHDOG_NOTICE);

I believe it should be:

watchdog('menu', 'Deleted key %key.',  $t_args, WATCHDOG_NOTICE);

because $t_args is already an array. I've been getting a preg_match error on my Recent Log Entries page because of this.
