I've seen this happen with no other activities having been run, so
it's not related to Musicpainter or Image Thumbnail.

I tried with on an XO with 10.1.2:

  1. boot the XO
  2. load Record
  3. record some video
  4. play back the video

I expected the video to be played back with full audio and video. What
I saw is playback for a few seconds, then it halts.

I'm having trouble reproducing. It seems to happen only on odd
occasions. I'll keep investigating.
