I'm pretty sure it's the "area_light" part of your light_source settings. 
Get rid of that, and it should look pretty good.  I guess this isn't a bug, 
because it's in the documentation.  I'm not aware of any way around it, 
other than getting rid of "area_light".

You can still use an area_light in your light_source block, but it seems to 
work better if you leave it out of the photon block.
