Description:
------------
Accessing a null object will only result in a notice if 
you are accessing a property but a fatal error if you are 
trying to access a method. 

This is especially strange if the object you expected to 
access uses __get and so you actually expect your code to 
fail.

I think at the very least that the notice should be 
upgraded to a warning. An error is also in place since 
accessing a member variable of a null value is most 
probably a serious problem in your application.

Reproduce code:
---------------
<?php
$var = null;
echo $var->member; // notice
$var->member(); // fatal error
?>
