probably because of this one: https://phabricator.freedesktop.org/T3452 I going build my own libnice to try this

[xelven]

after I build own libnice with OWR, seems this crashed not happened anymore now.

[stefanalund]

@xelven that is good news! Do you know when this fix will be part of an official release of libnice?

[xelven]

I would like make patch for this few days later if you want, because the latest libnice still have this issue.

@xelven Hi, we are banging our heads against that same crash...did you make a patch for it?, because we could surely use it! Thanks
