Backend Order Creation = PHP Fatal Error

[doomed999]

So I am having probolems with my emails going out, and was trying to test them by using the Send email button on the backend in a test order I created. I end up with a blank screen. I tried to manually create an order in the backend and get the same error.

I can't find any info on this anywhere I looked. Anyone have any ideas?

PHP Fatal error: Call to a member function setEntityId() on boolean in /var/www/html/app/code/core/Mage/Sales/Model/Order.php on line 1351, referer: https://mydomain.com/index.php/admin/sales_order_create/index/key/82694c394f6e20dc0b3ff67685c6c79d/

This same error also happens while I create the order from the customer side. The order creates, but no email go out. Not sure if they are related or not...

SELinux was the culprit of all of my email and error blues...
