Comment:

 I noticed that 'scale-changed' signal from SugarGestures.ZoomController is
 not always called with "scale" at 1.0 when I touch the screen with two
 fingers in my XO-4. Although, it is called properly in my XO-1.75.

 A test case is attached. It shows a red circle in the center of the screen
 when 'scale-changed' comes with "scale" == 1.0

 I sent an email to Carlos Garnacho.
