I see.  (But note that element_spec is documented as allowing NULL.)

Yeah, gperl_value_from_sv is not among them.  I guess we need to alter
Glib::Object::set_property to somehow cooperate with init_property_value such
that gperl_value_from_sv knows the expected element type when it encounters a
boxed of type G_TYPE_VALUE_ARRAY.  That won't cover G_TYPE_VALUE_ARRAY
arguments to signals or similar, but I don't see how to handle that
automatically.
