Error importing adsense api v3 wsdl with python-suds

This script

from suds.client import Client
server = "https://sandbox.google.com"
client = Client(server + "/api/adsense/v3/AccountService?wsdl")
print client

doesn't work with AdSense API v3:

$ ./v3_bug.py
Traceback (most recent call last):

suds.TypeNotFound: Type not found: '(Exception, http://www.w3.org/2001/XMLSchema, )'

If I change v3 to v2, everything works fine:

$ ./v3_bug.py 

Suds ( https://fedorahosted.org/suds/ )  version: 0.4 GA  build: R699-20100913

I know about doctors, but I don't know where the error is.
