Liliana’s new escape hatch is nice, and indeed GDK_PIXBUF_MODULE_FILE is
unset in
$ guix shell --pure viewnior webp-pixbuf-loader
$ echo $GDK_PIXBUF_MODULE_FILE
but it rebuilds the world. A security-relevant (?) upstream
introduction of GDK_PIXBUF_MODULE_PATH also would have Guix rebuild the
world.
Could I, with your agreement, push the viewnior wrapper patch with
(wrap-program viewnior
`("GDK_PIXBUF_MODULE_FILE" =
in the meantime? The majority of users will not know search paths
anyway perhaps, and viewnior is just one image viewer.
