Short description of error
Nurbs curve goes sharp when a point get copied and extruded

Exact steps for others to reproduce the error

Make a new nurbs curve object.
Go into the edit mode and duplicate any point.
Try extruding that point.
The curve goes sharp, and although it looks similar to polyline, corners are a bit rounded. However it doesn't look like a smooth nurbs curve at all.
Trying to set spline type to nurbs again doesn't solve anything.

When you created a single vertex, its order was set to 2 and further extruded vertices also inherit the order of 2. So just set it to the required order again (The default is 4).
