here's a workaround, at least: replace the path_close implementation 
with the following:

static PyObject*
path_close(PathObject* self, PyObject* args)
     if (!PyArg_ParseTuple(args, ":close"))
         return NULL;


     /* expand curves */
     agg::path_storage* path = self->path;
     agg::conv_curve<agg::path_storage> curve(*path);
     self->path = new agg::path_storage();
     self->path->add_path(curve, 0, false);
     delete path;

     return Py_None;

(not sure this is the best way to fix this, but it should hopefully get 
you going)
