Screenshot dir is not complying with xdg-userdir

[snaggen]

When I saw that screenshots would be stored in $XDG_SCREENSHOTS_DIR I added it to ~/.config/user-dirs.dirs
and verified that it worked by doing
xdg-user-dir SCREENSHOTS. However, it seems that that didn't work at all, it was still stored in ~/$XDG_PICTURES_DIR/Screenshots

and looking at the code

                std::env::var_os("XDG_SCREENSHOTS_DIR")
                    .map(PathBuf::from)
                    .filter(|p| p.is_absolute())
                    .or_else(|| {
                        // Fall back to XDG_PICTURES_DIR/Screenshots or ~/Pictures/Screenshots
                        dirs::picture_dir()
                            .or_else(|| dirs::home_dir().map(|h| h.join("Pictures")))
                            .map(|p| p.join("Screenshots"))
                    })

it currently only looks at the env. Which is quite weird, since the fallback actually handles XDG_PICTURES_DIR correct and then just attaches "Screenshots" to it.

I guess that the dirs crate needs to be patched to support XDG_SCREENSHOT_DIR and use that if set.

I'm also not able to set XDG_SCREENSHOTS_DIR, so that it will be used.
At the top of /etc/profile I set

export XDG_SCREENSHOTS_DIR="/home/snaggen/Bilder/Skärmbilder"

(ok, not pretty, but on my single user laptop I guess it should be ok)

And as a user I can do

$ echo $XDG_SCREENSHOTS_DIR
/home/snaggen/Bilder/Skärmbilder

Still when I take a screenshot it is stored in $XDG_PICTURES_DIR/Screenshots

So, how are users meant to set this value?
