I believe the problem is in the jabber code - on entering a venue, one  
of the VenueClient's tasks is to create and/or enter a jabber room  
with the same name as the venue. This fails with python 2.7 (for some  
reason) and prevents set up of the media tools, vic and rat.

I've verified this on a python 2.7 system by disabling text chat  
completely in the VenueClient.py and VenueCLientUI.py, after which I'm  
able to fully enter previously troublesome venues.

Although that appears to identify where the problem lies, the problem  
still needs to be fixed - I'm not sure who has time to look at that.
