it's not undefined, it's 0.
"scale 4.0*x" is exactly the same as "scale 4.0*<1,0,0>" or "scale 
<4.0,0,0>", so you're actively telling pov-ray to scale it infinitely 
thin in the y- and z-direction. It just assumes you meant to keep the 
dimensions in those directions, but it could just have assumed you 
really meant 0 and scale it as small as computationally possible.

At least, that's how I understand it :)
