(hello:94885): GLib-GIO-ERROR **: Settings schema 'org.gnome.settings-daemon.plugins.xsettings' does not contain a key named 'antialiasing'

Hi,

I ran try-reflex on a fresh archlinux with the standard gnome environment. When running the very first 'hello.hs' example from the nix-shell, the program crashes with the error:

(hello:94885): GLib-GIO-ERROR **: Settings schema 'org.gnome.settings-daemon.plugins.xsettings' does not contain a key named 'antialiasing'

the stack trace of coredumpctl reveals that there's some issue with the libgio-2.0.so.0, when calling g_settings_schema_get_value:

It seems that the gtk or gdk rely on a gnome schema, that is not present on my system.

EDIT: This happens both on the master and the develop branch.

Thank you for your support !
