Python 3.2 and GTK3

Hi all,

I cannot get the draw signal to work in with Python 3. The following code is a bare bones examples of what I mean:

Code:

#!/usr/biqn/env python3.2

from gi.repository import Gtk, Gdk
class MyExample(object): 
  def __init__(self, user_data=None): 
    window = Gtk.Window() 
    window.connect("destroy", Gtk.main_quit) 
    drawing_area = Gtk.DrawingArea() 
    drawing_area.set_size_request(300,300) 
    drawing_area.connect('draw',self.expose) 
    window.add(drawing_area) 
    window.show_all()  

  def expose(self,widget,cr): 
    print ("self_exposed") 


# === 
if __name__ == "__main__": 
    app = MyExample() 
    Gtk.main() 

It runs fine with 2.7, but on 3.2 the screen appears but the expose function never seems to run and when I quit the program I get the following message:

Quote:

Exception TypeError: TypeError("Couldn't find conversion for foreign struct 'cairo.Context'",) in <module 'threading' from '/usr/lib/python3.2/threading.py'> ignored

I am using Linux Ubuntu 12.04. This problem has been encountered on other forums with no solution proposed.

Thanks for any ideas.
