SVN commit 539979 by cgilles:

digikam from trunk : RAW decoding and ICC color management workflow into image editor: If "using embeded ICC profile into RAW file" dcraw option is used, disable Image Editor color management.

IMPORTANT : there is a full description of the ICC color management workflow with RAW files in the DImgInterface::slotImageLoaded() method from dimginterface.cpp. Please take a look...

Gerhard : please check these description to write the digiKam handbook. Thanks in advance...
