light leakage reported for 5D MkIII

About 10 users have confirmed the same problem.
Basically, outside light is reaching the sensor through the top LCD panel area.
The original poster recommends the following test:

Remove lens and place the body cap.
Put on the eye-piece cover.
This should theoretically block any light from entering the camera.
Set ISO to 800 and set shutter mode to Av.
You should see a shutter speed of around 10 sec.

Now either shine a flashlight near the top LCD panel area or simply turn on the backlighting of the top LCD panel.

This will cause the shutter speed to fluctulate between 5-8 seconds, indicating light leakage.
