[libnice] 'should not be reached' on Android, GStreamer 1.18.3, webrtcbin

Hi there,

Starting with a working Android client version using libwebrtc, I have been
investigating switching to GStreamer & webrtcbin & have a *lot* to learn
:)  The client runs against a Medooze back end using ice-lite.

Using GStreamer 1.18.3, I see a bunch of lines like this and wondered if
they highlight a setup / configuration problem in my code?
../agent/address.c: line 206 (nice_address_set_from_sockaddr): should not
be reached
../agent/address.c: line 346 (nice_address_is_private): should not be
reached

I have included related log lines below. Apologies for including this much
text, hope that's OK. I can provide additional log output via whatever
route, if helpful.

thanks in advance for any insight you can provide,

Tom Gilbert
