Does this look like an issue with my inkscape installation? I installed it using MacPorts:\n\n```\n$ inkscape --version\nInkscape 0.48.2 r9819 (Mar 20 2012)\n```\n","author":{"url":"https://github.com/astrofrog","@type":"Person","name":"astrofrog"},"datePublished":"2012-03-22T13:15:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/787/matplotlib/issues/787"}
