Distribution/Version: Fedora Core 4 Test 2

I've attached a simple file that causes the crash. I will paste a section:    
    
        Gtk.init(args);    
        Button button = new Button();    
        int id = button.addEventHandler("activate", "test", this);    
        button.removeEventHandler(id); // <-- this causes the crash    
    
The crash also happens if I do:    
    
        ButtonListener listener = new ButtonListener() {   
            public void buttonEvent(ButtonEvent event) {   
                System.out.println("test");   
                   
            }    
        };   
        button.addListener(listener);   
        button.removeListener(listener);   
   
I've just used Button as an example here, but the problem happens with any   
subclass of GObject as far as I can see.   
   
I reproduced it with gij and jdk 1.5.0_02. CVS Head and libgtk-java 2.6.1.1.  
  
gij left the following message on the prompt: 
 
(java-gnome:5279): GLib-GObject-WARNING **: instance of invalid 
non-instantiatable type `(null)' 
 
(java-gnome:5279): GLib-GObject-CRITICAL **: g_signal_handler_disconnect: 
assertion `G_TYPE_CHECK_INSTANCE (instance)' failed 
 
I'm also attaching the .log file created by sun's jdk.
