Description:
------------
I downloaded a liberty discovery wsdl from http://
www.projectliberty.org/specs/liberty-idwsf-disco-svc-v2.0.wsdl 
placed in my local directory and then pointed my php script at 
it.  I have some supporting XSDs but probably not all of them 
in that directory.  Output of my ls *.xsd follows:

liberty-idwsf-disco-svc-v2.0.xsd  liberty-idwsf-utility-
v2.0.xsd  ws-addressing-fragment.xsd

the problem is that the new_tns pointer is NULL and the 
expected error msg tries to dereference it.

Reproduce code:
---------------
<HTML>
<BODY>
<?php
$client = new SoapClient("file:///home/jwarring/cvs/discovery/docs/liberty-idwsf-disco-svc-v2.0.wsdl",
                         array ("trace" => 1, "exceptions" => 0));
?>
</BODY>
</HTML>


Expected result:
----------------
a complaint about not being able to find liberty-idwsf-
utility-v2.0.xsd

Actual result:
--------------
