Another issue is that if we pass undef as application id to
Gtk3::Application->new,
we got the following error:
GLib-CRITICAL **: g_variant_new_string: assertion 'string != NULL'
failed at /usr/lib64/perl5/vendor_perl/Glib/Object/Introspection.pm
line 67.

If we pass "" as id, we got:
(process:16552): Gtk-CRITICAL **: gtk_application_new: assertion
'application_id == NULL || g_application_id_is_valid (application_id)'
failed


However the doc does say a NULL value is OK:
https://developer.gnome.org/gtk3/stable/GtkApplication.html#gtk-application-new

And the annotation looks OK to me:
 grep -A4 'parameter name="application_id"'
/usr/share/gir-1.0/Gio-2.0.gir |grep -B4 "the identifier for
@applicatio"
          <parameter name="application_id"
                     transfer-ownership="none"
                     nullable="1"
                     allow-none="1">
            <doc xml:space="preserve">the identifier for @application</doc>
