Beach demo: strafing left and right broken

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Load beach demo
2. Press the 'a' or 'd' key to strafe left or right

What is the expected output? What do you see instead?
Expected:
The camera location moves in the scene horizontally left and right

Actual:
Camera does not move and the viewport flashes brown as if there were no content 
there.
