The little program below leaks memory like there is no tomorrow.
it is a pruned down screen saver framework.
Do not run for too long as it will bring you xserver down.

package version is
python-pyglet 1.1.2.dfsg-1

On another machine running hardy and a package from here
https://launchpad.net/~xeiso/+archive/ppa/+build/768951

The problem does not exist.

#!/usr/bin/python

import pyglet
import numpy

DIM_X = 600
DIM_Y = 1200

image = pyglet.image.create(DIM_Y+2, DIM_X+2,
                           pyglet.image.CheckerImagePattern())

window = pyglet.window.Window(DIM_Y+2, DIM_X+2)

rgba = "\0" * (4 * (DIM_X+2) * (DIM_Y+2))

@window.event
def on_draw():
   global image
   global rgba

   # comment out any of the two lines below and the leak goes away
   image.get_image_data().set_data('RGBA', 4 * (DIM_Y+2), rgba)
   image.blit(0, 0)

# schedule an empty update function, at 60 frames/second
pyglet.clock.schedule_interval(lambda dt: None, 1.0/60.0)

pyglet.app.run()

Which version of Ubuntu is affected by this bug ?

Wow, I had totally forgotten about this bug.

I believe it occurred on Jaunty (the other possiblity is Intrepid).
I recently switched to Karmic - will try to reproduces it there.
