IndexError: list index out of range

[2004seraph]

I try to scan my home network with:
upnp = upnpy.UPnP()
upnp.discover()

But I get the error:

Traceback (most recent call last):

I updated from 1.1.6 to 1.1.8 but I got another error with the same code:

AttributeError: 'NoneType' object has no attribute 'nodeValue'

FWIW: I've got the same Traceback with upnp 1.1.8.

The traceback occurs immediatly, so not after discovering stuff.

No problem with CLI tool mini-upnnc and with python module https://github.com/flyte/upnpclient. And yes, there is UPnP IGD on my network: my Internet gateway.
