Comment 1

[Andrew McCreight [:mccr8]]

I'm not sure why there's no message in the log, but as of right now, that's crashing on this code: case ChannelConnected: MOZ_CRASH( "MessageChannel destroyed without being closed " "(mChannelState == ChannelConnected)."); break;

Comment 2

[Andrew McCreight [:mccr8]]

Given the ~GMPServiceChild in the stack, this is probably a dupe of some other bug on crashes in GMP teardown that are already on file.
