Issues opening software through gtk portal

I have been using xdg.portal.xdgOpenUsePortal for a while to work around the issues when opening stuff from an FHSenv’d program.

After a recent nixpkgs update, this started causing any xdg-open command to fail, with GTK portal popup saying there are no apps installed that can open this software.

I didn’t see any recent Nixpkgs commits touching either the GTK portal, xdg-open, or the xdgOpenUsePortal option. Has anybody else started having issues with it?

Probably should’ve thought to test it, but the issue effects any programs that try to apps using portals, so trying to open anything from a flatpak fails.

I screwed up tracking my rebuilds when testing. It’s an issue going from nixos-cosmic to the nixpkgs cosmic module.
