           Summary: ICC Convert faulty in BQM
           Product: digikam
           Version: 1.2.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: michal at thoma.cz

OS:                Linux
Installed from:    Ubuntu Packages

ICC Convert function in BQM is faulty, because it changes only color values,
though no ICC Color profile tag. 

So if you convert AdobeRGB image to sRGB, color managed display will be wrong,
because this sRGB color space image will be identified a treated still as
AdobeRGB (according to color profile tag).

How to reproduce: 

1 - Take image in any known and set color space (i.e. sRGB).
2 - Put it to BQM and set Convert ICC to some other color space (i.e.
ProPhotoRGB) and process it.
3 - Check visual differences between converted and original image. Check color
profiles of both images with Color tab at right sidebar.
