This is not the case though, the modifier act explicitly on mesh edges, if no tesselated mesh is provided, it would simpy early out and do nothing. Now always disable the "Apply on Spline" option with a tip that this modifier can only smooth the tesselated curve (not the underlying curve control points). Similar to rB1a6b51e17502. Fixes T102060.
