The changes that were needed to make PyGI (and hence Zhaan et. al) happy were pulled into the gupnp, gupnp-av master branches these past couple of days and this morning Zeeshan made a release (13.3) containing these changes. You can find Zeeshan’s announcement here.
A huge thanks goes to Zeeshan Ali (Khattak) and Ross Burton for helping to get these changes through!
