error calling client method without parameters

Using Python 2.7.3 and IPython:

In [1]: import pysimplesoap 

In [2]: pysimplesoap.__version__
Out[2]: '1.10'

In [3]: client = 
pysimplesoap.client.SoapClient(wsdl="http://cpdb.molgen.mpg.de/download/CPDB.wsd
l")

In [4]: client.location
Out[4]: u'http://cpdb.molgen.mpg.de/ws2/'

In [5]: client.namespace
Out[5]: u'cpdbns'

In [6]: client.getCpdbVersion()

    286         # parse results:
    287         resp = response('Body', ns=soap_uri).children().unmarshall(output)

    212         return response

SoapFault: SOAP-ENV:Client: Unparseable message

Since the message is unparseable, I constructed it myself and tried, which 
works:

In [7]: params = pysimplesoap.simplexml.SimpleXMLElement("""<?xml version="1.0" 
encoding="UTF-8"?>                             
<getCpdbVersion></getCpdbVersion>""")

In [8]: response = client.call("getCpdbVersion", params)

In [9]: response
Out[9]: <?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope 
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:ZSI="http://www.zolera.com/schemas/ZSI/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><SOAP-ENV:Header/><SOAP-EN
V:Body 
xmlns:ns1="cpdbns"><ns1:getCpdbVersionResponse><ns1:cpdbVersion>cpdb28</ns1:cpdb
Version></ns1:getCpdbVersionResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>

So the proper result is in there. so what's going wrong before?

In [10]: operation = client.get_operation("getCpdbVersion")

In [11]: client.wsdl_call_get_params("getCpdbVersion", operation["input"])
Out[11]: ('getCpdbVersion', {})

In [12]: client.call("getCpdbVersion", *{})

SoapFault: SOAP-ENV:Client: Unparseable message

If this can somehow be easily fixed, I'm willing to provide a patch but I'm not 
sure where to start right now.
