It looks like the QtSvg module is targeting SVG Tiny 1.2, which does not support clipping:
http://doc.qt.nokia.com/4.3/qtsvg.html SVG Tiny also limits a lot of the CSS styling things that matplotlib makes use of -- though those things are probably easier to workaround if necessary. So, it's not broken so much as scoped below the threshold of usefulness ;) A possible workaround would be to add vector clipping to matplotlib and perform it before output. This has the nice side benefit of reducing file sizes (in many cases). However, that's a pretty major project to get right. I haven't had a chance to look at the new Qt shell in ipython yet -- but is it necessary to go through a file? Perhaps writing a native Qt4 backend (rather than the Qt4Agg one we currently have) would allow this to work better. The Qt4 rendering infrastructure itself does seem to support clipping.
