MindTouch Add Script Blank Page

MindTouch 10.0.8 with PHP 5.3.3, navigating to Extensions > Add Script renders a blank page, and no errors thrown in the Apache log.

It looks like PHP 5.3 has different behavior for call_user_func_array, change MINDTOUCH/deki/cp/extensions.php:189 to warp the parameter as an array:

$this->executeAction('add', array(true));
