Thanks for the fix!  It works.

However, another crash sometimes happens when adding large amplitude
noise before Polygonalization modifier.


1. Start Blender and use default cube
2. Enable Freestyle
3. Add a line set
4. Add geometory modifier "Perlin Noise 2D" and set Amplitude=1000
5. Add geometory modifier "Polygonalization" and set Error=1.0
6. Start render by F12

Blender may (or may not) crash after getting warnings like
"strip vertex XXX non valid".
