Steps to reproduce the problem:
1. go to some room on appear.in
2. turn the camera off by clicking the "cam off" button
3. this sets the tracks enabled attribute to false and stops the track 5 seconds later
4. turn the camera on again by clicking the same button. This calls getUserMedia again and resets the srcObject

What is the expected behavior?
self-image works

What went wrong?
self-image is frozen at the first frame. The video elements webkitDecodedFrameCount continues to increase.
