Here the correct script that produced the bug and the stacktrace

I posted a simpler python script. I tried to run the this script with the last ubuntu 9.10 alpha version using a intel 965 and a nvidia 8600 GT with driver nv and the same error occurs. Then I tried with the proprietary nvidia driver and the error doesn't occurs. I think the error is in libgl1-mesa-glx. In Fedora 11 with mesa-7.6 version, this doesn't occurs too.

Ubuntu 9.04 and 9.10 64 bits don't have this problem.

This bug affects me too.

Sorry forgot to mention coniguration:
Ubuntu 9.10, i386, asus eee-901 laptop

[amdlin (amdlintuxos)]

me again, i don't know is this fix or not, but now it works for me.
all that i did is just installed

Installed the following packages:
freeglut3 (2.4.0-9)
glutg3 (3.7-25)
libglut3 (3.7-25)

Hope that will help others
Now demos from pyopengl works!

Python crash with SIGSEV on my pc too. It happens with all OpenGL/GLUT script. For example:

from OpenGL.GLUT import *
from OpenGL.GL import *

def init():
    glClearColor(0,0,0,0)
    glMatrixMode(GL_PROJECTION)
    glLoadIdentity()
    glOrtho(0,1,0,1,-1,1)

def display():
    glClear(GL_COLOR_BUFFER_BIT)
    glColor3f(1,1,1)
    glBegin(GL_POLYGON)
    glVertex3f(0.25, 0.25, 0)
    glVertex3f(0.75, 0.25, 0)
    glVertex3f(0.75, 0.75, 0)
    glVertex3f(0.25, 0.75, 0)
    glEnd()
    glFlush()

if __name__ == '__main__' :
    glutInit()
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB)
    glutInitWindowSize(250, 250)
    glutInitWindowPosition(100, 100)
    glutCreateWindow("Hello World")
    init()
    glutDisplayFunc(display)
    glutMainLoop()
