Whenever (or almost) I open a .NRW raw file from my Nikon CoolPix P7100, or try to change the temperature or green factor in manual white balance I get the following error popu:

Image: ChannelMultipliers: Value 0.000 too small, 
truncated to 0.100.

I do not see the error with .CR2 files from a Canon.

Does anyone have any clue as to what might be the cause?

James.

P.S. I did send some WB values to Udi for this Camera.
