I don't see such problem in my installations.
I may be wrong but It seems to me that it is a font issue (I believe
you're not using usetex mode).
Can you try to use other fonts?
For example, my current installation picks up the following font (Vera Serif?).
In [10]: matplotlib.font_manager.findfont(None)
Out[10]: '/astro/research/jul27/local/lib/python2.5/site-packages/matplotlib/mpl-data/fonts/ttf/VeraSe.ttf'
