At the time the photons feature was added, a significant part of the 
tracing code was duplicated in the photons tracing code. When a trace 
related feature is updated, we have to remember to duplicate the feature 
update in that photons code.

I'd guess this didn't happen - at least not correctly.

I'll look at this tomorrow.
