Summary: glCallList fails on nurbs surface

Initial Comment:
molehill.c compiles and renders fine
http://www.opengl.org/resources/code/samples/mjktips/grid/molehill.c

however, upon running molehill.py
/usr/local/lib/python2.6/dist-packages/PyOpenGL-Demo/GLUT/molehill.py

i get the following error, and the window does not display

Traceback (most recent call last):
  File "_ctypes/callbacks.c", line 295, in 'calling callback function'
  File "molehill.py", line 46, in display
    glCallList(THE_LIST)
  File "/usr/lib/pymodules/python2.6/OpenGL/error.py", line 208, in glCheckError
    baseOperation = baseOperation,
OpenGL.error.GLError: GLError(
        err = 1282,
        description = 'invalid operation',
        baseOperation = glCallList,
        cArguments = (1L,)
)

similar code that uses display lists with nurbs curves DOES work, somehow.

system info:
ubuntu maverick, python 2.6.6-2ubuntu2
python-opengl 3.0.1~b2-1
libglut3 3.7-25
libgl1-mesa-* 7.9~git20100924-0ubuntu2

OpenGL renderer string: Mesa DRI Intel(R) 945GME GEM 20100330 DEVELOPMENT x86/MMX/SSE2

arg, sourceforge won't let me log in.
