I suspect this bug is specific to the macosx backend. Can you switch to
another backend and confirm it doesn't happen there? (I can't reproduce
it on Linux).

Then I looked into the
file /Library/Frameworks/EPD64.framework/Versions/7.2/lib/python2.7/site-packages/matplotlib/patches.py
at the line 384 the code is: gc.set_linewidth(lw)
I added "lw = np.float(lw)" before "gc.set_linewidth(lw)", then the
example code runs successfully.
Any help?
Thanks for any reply.
