ZeroDivisionError when drawing axis

I do not get this error running the matplotlib
examples/contour_demo.py with matplotlib CVS

peds-pc311:~/python/projects/matplotlib/examples> python contour_demo.py --verbose-helpful
matplotlib data path /usr/share/matplotlib
loaded rc file /home/jdhunter/.matplotlibrc
matplotlib version 0.81alpha
verbose.level helpful
interactive is False
platform is linux2
numerix Numeric 24.0b2
font search path ['/usr/share/matplotlib']
loaded ttfcache file /home/jdhunter/.ttffont.cache
backend GTKAgg version 2.4.1
Traceback (most recent call last):

My best guess is that your Numeric version 23.1, is too old. Could
you upgrade Numeric and try again?

Thanks!
