I can confirm this bug on matplotlib-0.99.0, and 0.99.1.2, but not on SVN head. I think this is related to a recently fixed bug involving the renderer outputting single-point lines (which obviously doesn't make sense, and Postscript has problems with).
You can either install from SVN (I recommend using the 0.99.x branch [1], rather than the trunk), or set the rcParam 'path.simplify' to False. Unfortunately, the latter will result in some very large file sizes.
