Probably not a coincidence that this happened during test_bug1002702.html.

I'll look at this next when I return from PTO next week.

This is essentially a failed MessageChannel::AssertWorkerThread() which gets called from many different paths.  We're probably going to need a stack or a lot of instrumentation to determine what is happening here.
I believe this is a rare case where MessageChannel::OnChannelConnected() is called after the IPC actor is destroyed.
If we can reproduce this, then we might be able to use the patch from bug 969146 to get a stack out of the b2g emulator failure.
So far I have not been able to reproduce this outside of my suspect patches to close the actor soon.  Since we're not going with that solution its unclear to me if thats actually the same error or not.

At this point I'm inclined to wait and see if this manifests again.  So far we've only seen 3 stacks over 3 weeks and none in the last 10 days.
So far the try build in bug 1049801 comment 31 seems to address this.  Triggering a few more runs.

Looks like this was indeed fixed by bug 1049801.
