There's a catch noted at the top of the expression.
(vcunat moved it there from the commit message)

+/* Beware!
+After starting Guake it will give the error message "Guake can not init! Gconf Error. Have you installed guake.schemas properly?",
+which will have to be resolved manually, because I have not found a way to automate this, without being impure.
+
+If you have Guake installed, you can use `nix-build -A gnome3.guake` to get the path to the build directory in the nix store,
+which then can be used in the following command to install the schemas file of Guake:
+gconftool-2 --install-schema-file /path/returned/by/nix-build/share/gconf/schemas/guake.schemas
+
+It can be removed again by the following command:
+gconftool-2 --recursive-unset /apps/guake
