This will be a problem for us if we want to use Inkscape's PDF+LaTeX export functionality to get nice-looking text.\r\n\r\nMy current hypothesis is that Inkscape gets confused by its own `sodipodi`-namespaced metadata, which it may not expect to survive enclosure in a `<symbol>`.  (I can't reproduce the bug on files not containing `sodipodi` metadata, but I haven't tried very hard.)\r\n\r\nIf removing that metadata doesn't fix the problem, we should find an XML testcase reducer and find minimal tiler outputs that make Inkscape's rasterization differ from rsvg-convert's by more than N%."}}
