I agree it shouldn't copy a .desktop file into .config/autostart/. In
this case, the offending code is here¹, so there's not much that can be
done about it. In mine I've changed the Exec line to
/var/guix/profiles/per-user/... so it'll work as expected. In this case
the code generates a desktop file on the fly, so modifying the .desktop
file shipping with applications wouldn't even help here.
