For anyone reading this in the future....

It is an issue that will manifest itself on one version of php and not another but the MyDEBUG can be ignored.

DrByte says:
It's a PHP 5.4 issue, where the use of an object element (in this case $pInfo) is assumed to already exist, but in this specific case it doesn't yet. So, the message is telling you that it created the object on-the-fly for you.
