UndefinedInterfaceName exception when used with gSoap 2.7 client

[André]

I'm using Ladon 0.8.1 to expose SOAP services to a C/C++ client written on top of gSOAP 2.8.4 (Ubuntu 12.04 package).
When I tried to connect to my service the ladon-ctl testserver raised a UndefinedInterfaceName exception.

Using Wireshark I could see the client request and ladon-ctl stacktrace, see wireshark_soap.raw attached.
I'm not sure if it's the client that does malformed POST request or the server that doesn't handle it correctly, but I made a patch (ladon_parse_path_info.patch attached) for ladon/server/wsgi_application.py that solves the issue for me.
I've also attached a simple project (code.tar.gz) containing the Calculator web service and the gSOAP client source and Makefile for reproducing the issue.
