I attach a tiny test-image. OK the text is german. But it should be obvious.
The image contains an embedded profile "colorspin" that is mainly a sRGB-profile, but spins the colors.
Open the images in PWP, don't convert to the working space, press the clipping button and see what happens.

P.S.: I hope the forum software will not drop the profile
P.S.2: I just found out, that the forum software strips the profile. I will send the image per email.

There were several problems with the way monitor profiles were specified in the Color Management dialog box that I have fixed for the next release.

Winfried,

Could you please post a zipped copy of Frarbkreis.jpg that would preserve its ICC, or maybe its colour profile so that I can attach it to it? Thanks!

ok, I attach the *.icm/*.icc -File as a zip-file
The profile is named icc-virus.icm. This is also the internal name.
Some programs list the profiles by their file-name and some by their internal name.

Of cause it is not a virus :-)
I choose this name to point out, that using this profile for instance as your monitor profile will cause a lot of fun (or despair) by showing which programs use monitor profile. Using this profile needs some colormanagement knowledge.
You use it on your own risk.

Cheers! It's an excellent test image to detect if the output/display is colour-managed!

I found a similar idea here (the top 'red' truck images: left in sRGB, right with rotated colours but also in counter-rotated colour space):
