Yes, I plan to update my version of IC asap; thanks. Although, it's still not
clear to me why a JPEG image needs a color profile, or *doesn't* need one.

I also came across this, which explains some of the reasons for ICC profiles,
why some image file types don't have embedded ones, etc. I can't say if this is
a 'definitive' explanation, but it describes the basics at least. (Although, the
opinion there about the sRGB color space might be controversial.)

Interestingly, the article says something like, "GIMP expects to see an embedded
color profile when it loads an image"... but apparently it doesn't WRITE a
profile to an image. That's a bit strange ;-)

The comments from Ive and Clipka have raised some interesting questions, IMO.
