And the Answer is....

error_bound in the radiosity settings was reduced from 1.2 to 0.1

The intresting thing is that the lower the value the more accurate.  If you
look at the image on the left you can see that swathes of "radiosity" are
pasted across the front of the text, which strictly speaking is wrong
because its the back of the text that is giving off the light.  So the
higher setting of 1.2 was putting light when it should not been.

You may actually have to be a PovRay weenie like me to find that
interesting.
