Hi list.

I have this code, and under some conditions it makes my program to end

str=g_strdup_printf(
       "select producto as codigo,(select nombre from productos where
id=producto) as descripcion ,sum(cantidad) as cantidad from detalles
where fecha>=(select fecha from cierres where turno=%d and caja=%d)
and fecha<=(select fecha from cierres where turno=%d and caja=%d)
group  by producto order by codigo",
   
gtk_spin_button_get_value_as_int(GTK_SPIN_BUTTON(lookup_widget(widget,"desde"))),
    boa_fe.caja,
   
gtk_spin_button_get_value_as_int(GTK_SPIN_BUTTON(lookup_widget(widget,"hasta"))),
    boa_fe.caja
    );

 cmd = gda_command_new (str, GDA_COMMAND_TYPE_SQL,
GDA_COMMAND_OPTION_STOP_ON_ERRORS);
 recset = gda_connection_execute_single_command (boa_fe.conn, cmd, NULL);
 g_free(str);

 gnome_db_grid_set_model (grid,recset);

 g_object_unref (G_OBJECT (recset));
 gda_command_free (cmd);


Im getting this warning:(fiscal:21716): GLib-GObject-WARNING **:
invalid uninstantiatable type `<invalid>' in cast to `GObject'

(fiscal:21716): GLib-GObject-CRITICAL **: g_object_unref: assertion
`G_IS_OBJECT (object)' failed


Thanks.

Saludos, Juan Pablo.
