[SIP Beyond VoIP] Unicode issue with command line client

I have successfully compiled Blink as well as the command line sipclients on 64bit Fedora 15.
However, no audio devices seem to be recognised as of yet - in neither. I have followed the
steps for routing the requests to the audio card via the PulseAudio sound server, but this
has not worked yet. Anybody any further hints? Is there a way to use Qt's multimedia
framework instead of directly trying to talk to PulseAudio?

When using the command line chat client for testing, outgoing chat seems to work fine.
However, when the other party starts typing I get this output and the connection is

File "/usr/lib64/python2.7/site-packages/twisted/internet/base.py", line 789, in runUntilCurrent

ValueError: Unicode strings with encoding declaration are not supported.

This seems Unicode related.
