[Ruby] GTK2: aiuto programmazione GUI

[Aki]

Ciao a tutti,
ho questo listato in ruby-gtk2 (sono sotto win2000):

#!/usr/local/bin/ruby
=begin
  helloworld.rb - Ruby/GTK first sample script.

  $Id: helloworld.rb,v 1.5 2003/04/01 16:21:19 mutoh Exp $
=end

require 'gtk2'

Gtk.init

button = Gtk::Button.new("Hello World")
button.signal_connect("clicked") {
  puts "Hello World"
}

window = Gtk::Window.new
window.signal_connect("delete_event") {
  puts "delete event occurred"
  #true
  false
}

window.signal_connect("destroy") {
  puts "destroy event occurred"
  Gtk.main_quit
}

window.border_width = 10
window.add(button)
window.show_all

Gtk.main

ma quando vado ad eseguirlo mi dà come errore:

(ruby.exe): GLib-GObject-CRITICAL **: gtype.c:2254: initialization assertion fai
led, use g_type_init() prior to this function
d:/ruby/lib/ruby/site_ruby/1.8/i386-msvcrt/gtk22.so: [BUG] rbgobj_define_class:
Invalid gtype [GrabStatus]

ruby 1.8.2 (2004-12-25) (i386-mswin32)


This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

perchè???

P.S. premettendo che ho correttamente installato sia ruby che il runtime gtk2

Non programmo in ruby ma Gtk.init non l'ho mai usato... prova a toglierlo
