For the time being I'm making use of a workaround with the exiv2 
commandline tool:
exiv2 -M"set Exif.Photo.ColorSpace Short 2" _dsc*.jpg

This works based on the following information

This is what digiKam expects:
TagName:               Type:     Value:    Translation:
Exif.Nikon3.ColorMode  Ascii  9  MODE1a    MODE1a
Exif.Photo.ColorSpace  Short  1  1         sRGB
Exif.Nikon3.ColorMode  Ascii  9  MODE2     MODE2
Exif.Photo.ColorSpace  Short  1  2         Adobe RGB
Exif.Nikon3.ColorMode  Ascii  9  MODE3a    MODE3a
Exif.Photo.ColorSpace  Short  1  1         sRGB

And this is what it gets:
TagName:               Type:     Value:    Translation:
Exif.Nikon3.ColorMode  Ascii  9  MODE1a    MODE1a
Exif.Photo.ColorSpace  Short  1  1         sRGB
Exif.Nikon3.ColorMode  Ascii  9  MODE2     MODE2
Exif.Photo.ColorSpace  Short  1  65535     Uncalibrated
Exif.Nikon3.ColorMode  Ascii  9  MODE3a    MODE3a
Exif.Photo.ColorSpace  Short  1  1         sRGB

So the MODE2 camera-setting isn't translated correctly. The fix is
that we set Exif.Photo.ColorSpace for every JPG-file with the filename
beginning with an underscore (_dsc*.jpg), defining fotographs
taken in MODE2.

I am creating a script around this, with which I will also fix the 
ISO-tag. For sake of efficiency in my workflow and the need of renaming 
outside digiKam (too many digits in the sequencenumber), I will do 
without the digiKam imagedownload for the time being. So I also need to 
take care of autorotation, for which I'm using exiftran.
Nevertheless, I hope you will solve this matter in due time, because 
this is not an ideal solution.
