[Twisted-Python] Raise soap faults

[Charles Moad]

	I have a soap server that I am trying to make handle errors correctly.
 When there is an error I just return a SOAPpy.faultType instance.  The
client should correspondlingly raise a python exception when it gets
this.  Unfortunately it looks like twisted is returning the faultType
instance as a valid response.  Here is the returned SOAP:

*** Incoming SOAP ******************************************************
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<pdbChainFileCompressedResponse SOAP-ENC:root="1">
<SOAP-ENV:Fault SOAP-ENC:root="1">
<faultcode>ArgumentError</faultcode>
<faultstring>Invalid PDB Code</faultstring>
</SOAP-ENV:Fault>
</pdbChainFileCompressedResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
************************************************************************

and the python result literally is:

<SOAPpy.Types.structType Fault at -1213565780>: {'faultcode':
'ArgumentError', 'faultstring': 'Invalid PDB Code'}

So the soappy client is treating this as a valid return value, and not
raising an exception like it should.

Any ideas?

Thanks,
