Description:
------------
I am trying to write a class which can be used statically e.g. Db::connect(); Db::query() etc. I also have a __call() method to be executed in case of calling an inexistent static method. But this does not work: PHP says that the method is undefined.

Reproduce code:
---------------
<?php
	class Db {
		
		...
		
		function __call($method,$args) {
			echo 'Method: '.$method.'<br />';
			var_dump($args);
		}
		
		...
	}
	
	# this works fine
	$Db = new Db();
	$Db->test();
	
	# this makes a PHP error
	Db::test();
?>

Expected result:
----------------
Method: test
Array()

Method: test
Array()



Actual result:
--------------
Fatal error: Call to undefined method Db::test() in ...
