Random lines popping up with Freestile when Sketchy

Question

When I render a simple animation with Freestyle (all default settings, except sketchy at 3 and the Bezier modifier at 50) I get this result on some frames:

There are some lines appearing out of nowhere. The model has a simple diffuse material (not rendered in passes). How can I solve this without losing the sketchy style?

Here is a succesful image:

And the blend file:

Frames 21 and 24 illustrate the problem.

Thanks in advance.

It's hard to tell without seeing your scene setup. Could you show a bit more? How many objects are there? Does the "random line" appear also in render from other camera's points of view (same frame)? — Carlo, Feb 08 '16 at 20:44

Play with the error settings for the bezier curve modifier:

Had the same issue. Tried your solution and no value worked. But hey, I removed the bezier and it saved my life. – Kiskit Nov 30 '18 at 15:10
