You've hit one of the changed APIs in 0.98. You can see the list of changed APIs here:
http://matplotlib.svn.sourceforge.net/viewvc/*checkout*/matplotlib/trunk/matplotlib/API_CHANGES Patches no longer store lists of vertices, they store Path objects + Affine transforms. So rather than "get_verts()", you can use the admittedly obtuse "circle.get_transform().transform(get_path().vertices)". Note also another change is required in your script for something that probably only worked by accident before. The "ax.add_patch(p)" should be "ax.add_collection(p)", since p is a PolyCollection. Now -- for the other developers on this list: We may want to add a .get_verts() function back to patches that does exactly what I recommend above. It won't behave identically to 0.91 since it will return a transformed copy of the vertices, but that won't matter in all cases (such as this one). We may want to add a PatchCollection class that takes a list of patches, so users don't have to manually take patches apart like this. This is now possible because all patches are basically the same thing. This would also make it easier to use an bezier-approximated Ellipse rather than a polygonal approximated one.
