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

[Egor O. Ivanov]

Hello,

I'm using libnice on ios and android. The code is the same on both and 
on iOS it worls perfectly, but fails on Android.
I do receive multiple "new-selected-pair-full" calls with correct 1st 
pair and wrong 2nd and 3rd.

  selected pair 1 : 1
  selected pair 3 : remote-1
  selected pair 8 : 3

The problem is that periodically I do receive weird 7 bytes in my 
receive callback.
I tried different versions 0.1.10 and 0.1.13, but no luck.

Thanks.
