Thank you, that was good.

I had /usr/share/gimp/2.0/, now, after (3 hours of) emerging gimp-help, I also have help/en/

Unfortunately, I still get the same error msg.

Here are my USE flags:

I have the feeling that, when gimp didn't see the help/ dir the first time, it set something, microsoft-like, in persistant storage, and doesn't even try to look locally anymore.

And why it can't access the xml file, which is there, I have no idea.  But I see no flags that look related to GIO or GVFS.

You have a lot of flags set... I hope I don't have to set those all, just to see if it helps...

After emerging gimp, I tried to get help (after re-emerging with the doc USE flag), and got this:

Could not open 'https://docs.gimp.org/2.10/en/gimp-help.xml' for reading: Operation not supported

Perhaps you are missing GIO backends and need to install GVFS?

Is there anything I can do?

When I open GIMP and go to help, it takes me here: 

file:///usr/share/gimp/2.0/help/en/index.html

It opens in Seamonkey for me.  Seamonkey is set as my default browser.  This is my USE flag settings.

These are the packages that would be merged, in order:

Do you have the gimp-help package installed?  If so, your USE flags match mine?
