Description

The following code:

<?php
$server = new soapserver(null,array('uri'=>"http://testuri.org"));
$fusion = $server;
$ao2 = clone $fusion;

Resulted in this output:

Bisect points to 94ee4f9, which is unsurprising as this is the second time I see this.
Thing is that that commit only reveals the problem. Cloning this object shouldn't be possible in the first place.
