  I don't know the exact reason, but it just doesn't work and I have the
impression that nobody developing the code even cares. The method is anyways
obsolete in pov3.5, so the problem will disappear by itself.

I would normally care, were it not for that "obsolete in 3.5" thing.

  I should have used a ':' instead of a '.' after the word 'cares' for
clarity, because that's what I meant :)

My guess is that the isosurface code relies on some global variables 
that aren't initialized until parsing is done...

This also explains why if you render the iso without the trace code, and
then add the trace code it works!
