Are you referring to

 http://git.gnome.org/browse/glib/tree/gio/tests/gdbus-testserver.py?id=2.33.8

I think that's the only place we use it. My answer to that is: sure, we should just rewrite gdbus-testserver in C.

(using GI inside GLib itself gives you boot-strapping problems since GLib and its GIR/typelibs is in another package. Very annoying.)

Would prefer something like

 g_assert (!g_variant_is_floating (ret));

just to check the invariant that only non-floating GVariant instances are in the hash table.

We should also set @error (suggest G_DBUS_ERROR_FAILED) if there is no property with the given @property_name - otherwise people reading the code will be led to believe that they can just return NULL without setting @error.

Should also set @error here.
