bug#74774: Commit 5d284ebc8df87b0e21cee5844d66dc7c80863464 breaks reconfigure for systems using gnome-desktop-service-type

[paul via Bug reports for GNU Guix]

Hi,

since 5d284ebc8df87b0e21cee5844d66dc7c80863464 it's not possible anymore 
to have gnome-desktop-service-type and xdg-destkop-portal-gtk installed 
in the system profile. Is this intended? Is there any workaround?

Thank you for your help,

giacomo
