Intermittent faliure in Paypal IPN return

I am having Intermittently an issue with orders paid via paypal, but no data inserted to zen_orders and no mail sent to customers. Usually when I try to order myself, all works fine.

The only clue I got is a debug message :

[19-jan-2010 14:32:56] PHP Fatal error: Call to a member function add() on a non-object in /home/content/m/i/n/mineralz/html/includes/classes/order_total.php on line 75

I can't see anything special in this file, nor I understand why it's called during checkout, that AFAIK uses URL like : index.php?main_page=checkout_process&referer=paypal&tx=123qwe123qwe123qwe&st=Completed...

I'm using Zen Cart 1.3.8a
PHP Version 5.2.8
GoDaddy Shared Linux hosting (with appropriate changes for godaddy applied to paypal ipn)

Any ideas ?

You'll want to implement this fix: http://www.zen-cart.com/forum/showthread.php?p=712287#post712287

Thanks for answering, DrByte, but this fix deals with issues in sending the order confirmation mail after checkout.

I am having problems before that, in order_total.php and not in functions_email.php, as in the bug description.

Would you recommend implementing this change anyway ?

And one more thing - does this mean that after implementing the fix, paypal_ipn.core.php will **NOT **have "?>" closing characters at the end of the file at all ?

The issue is that the $messageStack needs to be initialized ... which is what that fix accomplishes, regardless of the symptoms mentioned.
So, yes, you need to implement it.
