[libnice] multiple "new-selected-pair-full" calls and weird extra 7 bytes in receive callbacks

[Philip Withnall]

Hi,

I just tried to reproduce this locally (on Linux) and could not.

Could you please provide a copy of the SDP strings generated by libnice
using nice_agent_generate_local_sdp(), and the ones generated by the
manual handling? That might help me investigate.

Thanks,
Philip
