I'm not quiet sure how to fix this issue, but I think media will not 
help here. Glass has no media inside. This seems to be more a issue of 
refraction. The problem may be that POV cannot calculate different 
refractions for different wavelenghts at once by default. IIRC there is 
a work around utilising an animation and combing the results to a final 
image for this issue posted by Ive (IIRC again) some time ago to 
p.b.s-f. A search for "spectral rendering" should yield it (There were 
more than one posting).

Best regards,
Michael
