wxPython demo crash

When I run the glcanvas wxPython demo I get this:
http://www.deadbeefbabe.org/paste/4037
as soon as I click the Cone or Cube button.
The app just goes *poof*.
I can compile and execute the mesa/C demos and my own glut/python
application.

Compaq Presario 2500
Ubuntu 6.06
Gnome
Python2.4
wx2.6

Noel and Robin, _great_ book btw.
