These are the lines printed, as you can see there isn't yet a rtpproxy
running but it has been working in the tests without crashing. The config
is pretty standard so you'll see the usual routes. I've printed the line
number for an easy debugging.
I'm not 100% sure that it always happens in the same point. I'll try to
reproduce it and see whether following errors happen in the same point of
the config file.
