[Bug 981644] [NEW] 'Choose a picture' generates shifted picture when using 'Take Photo'

[Matthijs ten Kate]

Public bug reported:

Just take a look at the attached screenshot.
To clearly illustrate the issue, I held the cover of my copy of StarTrek First Contact in front of the webcam.

On my desktop with a separate USB webcam, I get the same result AND I am
also unable to take a second shot (image freezes after the first shot).
This might be related to the webcam being an old USB1 model.

If any more info is needed, I'll happily provide.
