Twitch Livestreaming Crash

I was going to record a 1.8 Survival Video, and I created a 14w25b world, all normal settings. I pressed F6 to start streaming, and approx. 5 seconds later the game exited out to desktop, not launcher (my preferences say it should exit to the launcher). I hope you can get it fixed for the 1.8 update!
