Roy,

About settings of ICC color correction during dcraw decoding (look last dcraw 
option of IO files setup), i will remove it because it too complex to manage 
like this. Only digiKam core must perform icc color corrections.

Also, there is no suitable way to check if dcraw have found an embeded icc 
profile.

Your viewpoint ?

Gilles
