Thanks for the suggestion.  It seems to make sense, so I modified the
package as you suggested [1]. Unfortunately I'm still getting the same
error.

The `pithos` script includes the line

  export
GI_TYPELIB_PATH=/nix/store/9imvrzskcak2998zj1242jxgl4p9m5dp-gst-plugins-base-1.4.1/lib/girepository-1.0:/nix/store/byi4j636s13m8w28nvqiakn6nzakmadr-gstreamer-1.4.1/lib/girepository-1.0:/nix/store/y06kp3fxw3r5r3nfkqzc8l3y7r3kvns0-libnotify-0.7.6/lib/girepository-1.0:/nix/store/4z6rr314xg1iszkn2wjvvl16yfmwgwa7-gobject-introspection-1.40.0/lib/girepository-1.0${GI_TYPELIB_PATH:+:}$GI_TYPELIB_PATH

so it looks like it is doing what it is supposed to.
