moniker interface cannot be found

[Rodrigo Moya <rodrigo gnome-db org>]

Hi!

Using libbonoboui-2.0, I'm getting this error while loading a
BonoboControl on a client:

===================================================
120		wid->priv->bonobo_widget = bonobo_widget_new_control (id, uic);
(gdb) 

gnome-db (pid:29829): Bonobo-WARNING **: Activation exception 'Moniker
interface cannot be found'

gnome-db (pid:29829): Gtk-WARNING **: A floating object was finalized.
This means that someone
called g_object_unref() on an object that had only a floating
reference; the initial floating reference is not owned by anyone
and must be removed with gtk_object_sink() after a normal
reference is obtained with g_object_ref().
121		if (!BONOBO_IS_WIDGET (wid->priv->bonobo_widget)) {
====================================================

the error seems clear (it can't find the moniker interface), but, which
moniker interface (OAFIID:?)? and how can I solve it?

cheers
