Hello, sorry my bad English. After upgrading to gnome-base/librsvg-2.40.20, X11-misc/xxkb failed with error " xxkb: SVG file `/usr/share/xxkb/en.svg': Operation not supported xxkb: SVG file `/usr/share/xxkb/su.svg': Operation not supported xxkb: SVG file `/usr/share/xxkb/ru.svg': Operation not supported" and no icons are shown. After downgrade to gnome-base/librsvg-2.40.18 everything works without problems.
