OpenVRML doesn't know about NurbsSurface. (It could probably be
implemented by twiddling the existing support for the X3D
NurbsPatchSurface node; however, note that OpenVRML is currently only
capable of constructing scene graphs with these nodes--rendering them is
not implemented.)

The assertion failure shouldn't happen; and in 0.16.3, it doesn't (for
me). You don't say what version of OpenVRML you're using.
