gupnp and python

[Andrzej Bieniek <andyhelp gmail com>]

Hi,

There are two patches [1][2] I had apply to get gupnp partially working 
with python, see examples in [3]. I was able to send UPnP commands, but 
unable to read any status/values (due to segfault workaround in second 
patch).

When I remove patch 2 I get segfault with the callstack below.
(running on Ubuntu 12.10)

Is there a known configuration where gupnp works with python?
I'm not sure if bug is in gupnp or somewhere else.
Is there something I can run/try to narrow down and potentially fix the 
problem?


It crashes on GetVolume call:
--- cut demo.py ---
if name == "GetVolume":
   data = {"InstanceID": "0", "Channel": "Master"}
   data_out = {"CurrentVolume": "" }
   service.send_action_hash(name, data, data_out)
--- cut ---

gupnp-python$ gdb --args /usr/bin/python demo.py
