Comment (by Algunenano):

 I've extracted the geometry and clip box that was used to call
 clip_by_rect:
 ```
 # SELECT ST_ClipByBox2D('POLYGON((1410 2055, 1410 2056, 1410 2057, 1410
 2055))'::geometry, ST_MakeEnvelope(-8.000000, -8.000000, 2056.000000,
 2056.000000));
 ERROR:  lwgeom_clip_by_rect: GEOS Error: IllegalArgumentException: Invalid
 number of points in LinearRing found 3 - must be 0 or >= 4
 Time: 0.654 ms
 ```

 The geometry has 4 points but after simplification they've fallen into a
 Line. I'm not sure yet who is removing one of the points.
