GIO file references not working

[AshleyYakeley]

This passes during testing, but fails in the installed version, both flake on NixOS, and deb on Linux Mint.

#!/usr/bin/env -S pinafore
let
    import "pinafore-gnome";
    using GIO;
in do
    mref <- fileMakeRef $ FileParseName "test/somefile";
    mf <- get mref;
    decode textMIME mf >- match
        Just t => write.Sink stdout.Env t;
        Nothing => writeLn.Sink stdout.Env "not text";
        end;
    end

Looks like I shouldn't be using the "parse name" for a path. Probably it happened to work in an earlier version of GIO, but not now.

Done.
