Wilson, bug https://bugzilla.mozilla.org/show_bug.cgi?id=1109240 seems to have caused this.

Does but 1107683 need to land with this? If not then we will need to back out this Gaia patch.

I'm getting an error around face detection on startup. I suggest we either back this out now, or wait for :mikeh to advise.

It worked last night. :/ Investigating.

I just reapplied the patch in bug 1109240 to a fresh pull/build of my gecko and gaia trees, and the Camera app works as expected, including face detection.

Okay, the problem only seems to happen when *re*opening the camera.

STR:
1. open Camera app
2. press Home button
3. reopen Camera app

Observed: spinner.

Expected: active viewfinder.

Follow-up is in bug 1109240.
