Symbian Camera: Viewfinder not visible with widgets

Viewfinder is not visible with widget-based application(s).

How to reproduce:
Test "camera" example application in multimedia repository.

When observed:
This happens with the current code in the multimedia repository master branch.
This did not occur with my test code until I added the rotation support and the changes made for the QML viewfinder on S60 5.0 (changes to common video outputs).
This makes me assume it's due to either of those 2 changes.

Other info:

• It's possible to hear the sound of the shutter on N8, so camera is indeed started
• After capturing image, when the snapshot (preview) image is taken off from the display, the viewfinders very bottom part is visible for a very short while

Guesses:

• Possibly either positioning or z-order issue?
