does it wander to the left, i.e pull itself that way, or does it drive straight and true but with the steering wheel off-centre? Agree with Chip - check steering is centred by applying full lock to lock (should be eaqual), it will help diagnose.
From the print-out of the settings it has quite a big thrust angle - the rear axle steers left slightly, pushing car right slightly - meaning that when they set the front straight on the ramp, the car actually needs to be steered slightly left to match the direction the rears are pointing. Quite common, though usually after a knock/repair job of some sort (though some say quite normal on French cars :S)
Yes, its not right, but the problem looks like it lies in the rear (from the print shown) not the front. Most people just correct the steering center to match the rear thrust angle, which works well enough for most people, and this probably has not been done, as others have already said.
If it has a pretty obvious, sharp pull to the left on all surfaces then it might not just be what I have suggested above.
