Camera app stops responding when swiping through open apps

[Richard Huddie]

mako 20131011

TEST CASE:
1. Load the camera app
2. Load another app, e.g. Contacts
3. Swipe from right to left to move from Contacts to Camera app
4. Swipe from right to left again to move from Camera back to Contacts
5. Repeat swiping between apps quickly, do not wait for the camera app to initialise fully

EXPECTED RESULT:
The camera app should continue to function fully

ACTUAL RESULT:
If the swiping is completed before the camera app has fully initialised (i.e. the shutter icon has changed from grey to white) then the camera app will no longer function. There will be no live preview and the shutter icon will remain greyed out. The camea app will display a static frame as the live preview.

Note that if the device is rotated then the camera settings icons will rotate correctly with the device, so the camera app is not completely dead. See attached screen shot which shows the permanently greyed shutter icon and a frozen preview.

The camera app will need to be re-started in order to take a picture again.
