Comment 10 for bug 685707

    confirmed, the file errorink.dxf contains some spline types that are not supported by the dxf import routine. These are cubic splines, not quadratic, so they are different than the problem originally reported here. They also contain more than 4 control points, so it will not be possible to represent them as a single Bezier spline.
    I do not know if it will be possible to represent these as some combination of Bezier splines, will need to think about that for a while...
