Hey,

If current versions of UFRaw are built against LCMS2 (which should be
common by now), the embedded sRGB profiles are automatically upgraded to
ICCv4 (as opposed to ICCv2 with LCMS1).

This has some side-effects:
- Windows XP's Picture Viewer breaks in bizarre ways if images have ICCv4
profiles embedded (not such a big issue anymore these days).
- We (=dt) have had reports of some chemical photo print workflow software
breaking on these ICCv4 embedded profiles as well.

In dt with the help of Marti, we've constructed an ICCv2 sRGB, which we
embed, I've ported this code to UFRaw, with permission of the original
author on our side (Tobias Ellinghaus), since effectively it's a relicense
from GPLv3 to GPLv2:

We also have similar AdobeRGB embedded profile, which I might port over if
you accept the above patch.

So what's the catch, well, this patch depends on LCMS2, and it seems UFRaw
still supports LCMS1, which my patch would break. Considering LCMS1 is
essentially unsupported/deprecated these days I personally don't see a big
issue with that. But you might of course disagree.

Please let me know your thoughts!

Regards,
Pascal de Bruijn
