$this->notify('NOTIFY_SHIPPING_MODULE_GET_ALL_QUOTES', $quotes_array, $quotes_array);

Is the duplication of , $quotes_array in the 1.5.5a file intended?
Yes, intended. And, unless you're actually using something that gets triggered by that notifier hook, it wouldn't be affecting your shipping. let alone taxes
