this is easy I think. You are not using the latest Subversion version 
ar you?

 From livedotcom.cpp:
int fd = sub->rtpSource()->RTPgs()->socketNum();

The VLC plugin always expects there to be a rtpSource()
In the kasenna situation however, there is only a readSource and not 
it's child (a rtpSource) available.
This is fixed with a if( sub->rtpSource() ) in the current development
