    Thanks for the quick answer.
    I am not on the box but I used master from yesterday, so
    89482b21c8582d49a2ddc2865e472eb404fd07e2
    <https://github.com/matplotlib/matplotlib/commit/89482b21c8582d49a2ddc2865e472eb404fd07e2>,
    I guess.
    The platform is Ubuntu Precise (with loads of random Python
    packages, but that seems somewhat unrelated).
    Cheers,
    Andy
