glade_xml_get_widget => SEGV

Hi,

trying to use glade_xml_get_widget(...)->allocation.x tells me: Segmentation fault :( although i followed the documentation.
What I need is the absolute position of the gtk/glade(xml) window and my source looks like:

Code:

---

int main2( int argc, char **argv )
{
        const gchar *home_path;
        gchar *full_path;
        GladeXML *xml;
        GtkMoz gmoz = { 0, 0, 0 };
        GtkEntryCompletion *comp;

        gtk_set_locale();
        gtk_init( &argc, &argv );

  home_path = g_get_home_dir();

  if( !home_path ){
    g_printerr( "Failed to get HOME\n" );
    return 1;
  }

        full_path = g_build_filename( home_path, ".gtkmoz", NULL );

        gtk_moz_embed_set_profile_path( full_path, "gtkmoz" );

        g_free( full_path );
       
        full_path = g_build_filename( home_path, "mozilla", "dist", "bin", NULL );

        gtk_moz_embed_set_comp_path( full_path );

        g_free( full_path );

        xml = glade_xml_new( "gtkmoz.glade", NULL, NULL );

        gmoz.moz_embed = (GtkMozEmbed*)glade_xml_get_widget( xml, "browser" );
        gmoz.url_entry = (GtkEntry*)glade_xml_get_widget( xml, "url_entry" );
        gmoz.txtUserAgent = (GtkEntry*)glade_xml_get_widget( xml, "txtUserAgent" );
       
        // set up entry completion
        comp = gtk_entry_completion_new();
        gmoz.entry_model = (GtkTreeModel*)gtk_list_store_new( 1, G_TYPE_STRING );
        gtk_entry_set_completion( GTK_ENTRY( gmoz.url_entry ), comp );
        g_object_unref( comp );
        gtk_entry_completion_set_model( comp, gmoz.entry_model );
        g_object_unref( G_OBJECT( gmoz.entry_model ) );
        gtk_entry_completion_set_text_column( comp, 0 );

        // set up signal handlers
        glade_xml_signal_connect( xml, "on_window1_destroy", gtk_main_quit );
        glade_xml_signal_connect_data( xml, "on_url_entry_activate", G_CALLBACK( load_url ), &gmoz );
        glade_xml_signal_connect_data( xml, "on_back_button_clicked", G_CALLBACK( back_button ), &gmoz );
        glade_xml_signal_connect_data( xml, "on_forward_button_clicked", G_CALLBACK( forward_button ), &gmoz );
        glade_xml_signal_connect_data( xml, "on_refresh_button_clicked", G_CALLBACK( refresh_page ), &gmoz );
        glade_xml_signal_connect_data( xml, "on_stop_button_clicked", G_CALLBACK( stop_button ), &gmoz );

        // connect gtkmozembed signals
        g_signal_connect( gmoz.moz_embed, "location", G_CALLBACK( update_url_entry ), &gmoz );

        g_object_unref( G_OBJECT( xml ) );
        refresh_page( NULL, &gmoz );

        gtk_entry_set_text( GTK_ENTRY( gmoz.url_entry ), "http://www.ipchecker.mb-media.at/sigtux_user.php" );

       
        gint wx, wy;
        //GdkModifierType state = (GdkModifierType)0;
        //gdk_window_get_pointer( NULL, &wx, &wy, &state );
        //std::cout << "\n\t" << wx << "; " << wy << "\n";
        std::cout << glade_xml_get_widget( xml, "browser" )->allocation.x; // => Segmentation fault (core dump)
       
        gtk_main();

        return 0;
}

I use glade_xml_get_widget( xml, "browser" ) two times, but the second time, when i want to get know details about the position of the widget/window, it dies :(

Hope for help.
Thanks.
Best regards
