Can you show me? Is the test wrong or an actual pc bug that should be filed? 

[phoglund_chromium, 2014/01/07 14:41:59]

I'm not sure. So what happens is that when we call negotiate() we do a
createOffer on the first peerconnection. The first negotiation round will move
it into the state have-local-offer, and as the call gets up the peerconnection
goes to stable. When we do the second negotiation round the peerconnection
doesn't go to have-local-offer but stays in stable. Not sure if that is a bug.
If it isn't, we need some logic in the test which says "expect the state to be
have-local-offer unless we have already negotiated once, in which case it should
be stable".
