PMC issue

I found a bug on how the PMC kernel renders certain types of surfaces in low light condition.
This kitchen is illuminated by 8 photometric lights, then I placed a blackbody in the ceiling lamp above the table and one more light in the hood.

If I use the PT this issue doesn't happen but isn't recommended to use ies lights with path tracing because the render will get a lot of noise, the only way is to render with the pmc kernel.

Take a look at this examples:
