That's been fixed in guix-install.sh with
23aafc800c9e678662766440916449ec5bbce830 from Philip McGrath (thanks!):
"etc/guix-install.sh: Initialize XDG base directories."

I've confirmed it fixes the original problem, which was that installing
'python-ipython' would break a GDM login to GNOME on Fedora, by
installing the latest Guix via guix-install.sh on a Fedora 33 VM I had
laying around, then 'guix install python-ipython', logout, then re-login
without an issue.

Closing!
