ni?ing aosmond.  Wasn't there a fix that you were implmenting against button mashing?

I can't repro this on today's nightly.  adding qawanted to double check (for me from 3rd or 4th start of the app, it instantly switches to the viewfinder mode)

Not for the home screen button. That might be challenging.(In reply to No-Jun Park [:njpark] from comment #3)

Hi Andrew,

    I can repro on latest Flame KK v2.5 and Aries KK v2.5. The key of this bug is that user should quickly tap Home button to exit before the camera view finder is opened, and repeat this operation for at least 5 or 6 times.

    Could you please take a look at this?

Thank you very much.

Actual results: The camera view finder is black, and user can not take photo or record video.

Huh. There are a few problems actually. We seem to be missing battery status updates (which means the camera controller thinks we are stuck on a low battery) and sometimes the mozCamera object doesn't exist when the zoom bar controller is lazily loaded (causing a JS error and stopping any more loading).

Bug 1189105 introduced the zoom related regression.

[Blocking Requested - why for this release]:

This is worse in current builds. It does not require button mashing. The user only has to press home while the camera is launching.

This issue is verified fixed on the latest Aries and Flame 2.5 master build.
Camera continues to work properly after repeatedly tapping the Home button right when opening the camera app. I used the STR in Comment 1, as well as the STR in comment 1 as well as the STR from bug 1208266.
