[OpenSCAD] Error importing STL.

I have an STL file that I want to print. The first attempt went bad
because the object didn't stick to the brim I ordered.
This occasionally happens, and I then add a cylinder with say 6 radius
and 0.6 height to the corners to make it stick better. The extra
material is easy to clip away after printing.
So I load this model
which is a "distributed" version of:
into openscad with
This views just fine (F5 - Preview), and renders too (F6-render).
Then I add one of my cylinders and it suddenly gets errors.... The
errors do not give any useful information as to what goes wrong:
When I hit "F6 - render", I get:
Compiling design (CSG Tree generation)...
Rendering Polygon Mesh using CGAL...
ERROR: CGAL error in CGAL_Nef_polyhedron3(): CGAL ERROR: assertion violation! Expr: pe_prev->is_border() || !internal::Plane_constructor::get_plane(pe_prev->facet(),pe_prev->facet()->plane()).is_degenerate() File: /usr/include/CGAL/Nef_3/polyhedron_3_to_nef_3.h Line: 251

in the log window, and many repetitions of:
in the stdout of openscad.
For "getting my print job done", it seems the github version is
"Better" in some way that it does not cause havoc with openscad.
I don't need help finding a workaround for this specific file: the one
from github works.
A better error message in openscad could help people less seasoned as
me in finding a workaround. I still need to print a few objects from
that set, so I would like to know WHAT is wrong, and how to fix/avoid

The plan was simple, like my brother-in-law Phil. But unlike
Phil, this plan just might work.
