[Done v1.5.5] PHP 5.4 warnings: Illegal string offset

[DrByte]

Using a stock v1.5.1 install (localhost) running php 5.4.8 on Windows 7. Added the product New v1.2 -> Downloads -> Single Download to my cart, signed in and clicked the Checkout button. I was properly redirected to the checkout_payment page, but had two debug*.log files generated:

In each case, the illegal offset is associated with an undefined array element. For example, line 355 of order.php contains:

                        'shipping_cost' => $_SESSION['shipping']['cost'],

I'm not quite sure how to proceed. Are these warnings indicative of something that might become errors in a future version of PHP?

'shipping_cost' => $_SESSION['shipping']['cost'],

The following changes are incorporated into the next ZC version to handle the errors reported in this thread:
