Crash in mozilla::Nr
Ice Ctx::Set Connection State
This bug was filed from the Socorro interface and is report bp-5d1f4743-d8d5-402d-9bdd-3605c2170308. ============================================================= There are 4 crashes in nightly 55 with buildid 20170308030207. In analyzing the backtrace, the regression may have been introduced by patch  to fix bug 1342523.  https://hg.mozilla.org/mozilla-central/rev?node=d99df97e4115adbc20a76be02407b74a508565bf
We're hitting an unexpected assertion here, which suggests there is a corner case that we did not anticipate happening, but it isn't scary or common. I suspect that what is happening here is a stream succeeds (ICE), and while we are waiting for the rest of the streams to succeed, consent times out. If this is true, it probably makes sense to treat this as a failure. What do you think Nils?

Either Consent timeouts during call setup or Necko telling us the network went offline while trying to establish the call. Either way I would prefer to not include this "edge" case into the failure category. So either just ignore it, or create a new telemetry probe just for this case. The latter might actually be helpful as time boxed thing (e.g. up to version 56 or something like that) to get an idea how common this "edge" case is.
I hit this on meet.jit.si, it was during call setup, when switched out to another tab (network state didn't change).
@bwc: the stack trace actually shows that we overlooked that the even though the switch checking->disconnected should not happen, the legit switch which trips over this is connected->disconnected. We could try differentiate between the two, but I'm not sure what we would gain by doing so.
