Patch SUPEE-10752 breaks checkout when using AMASTY module

[Sikanam]

It seems that the last patch SUPEE-10752 creates some issues with Amasty's One Step Checkout Module. When we try to make an order without being logged-in, using the Amasty's One Step Checkout Module, the system redirects on the home page, the customer is logged out with an empty cart, but the order is saved in the database.

Going deeper into my researches, I found that the problem was in the "app/code/core/Mage/Core/Model/Session/Abstract/Varien.php" file, from line 528 to 531 :

if (isset($this->_data['visitor_data']['customer_id'])) {
            $parts[self::VALIDATOR_PASSWORD_CREATE_TIMESTAMP] =
                Mage::helper('customer')->getPasswordTimestamp($this->_data['visitor_data']['customer_id']);
        }

When that part is commented, the bug no longer appears.

My website is under Magento 1.9.3.2.

I saw during my researches that Magento's team may be working on a v2 for the patch SUPEE-10752, can anybody confirm that surely ?

Cheers !
