That gives me some starting points as to where the problem might be.
I'll assume for now that the polygon geometries themselves can't be
the problem, then look downstream from there in the processing.

I'll check whether the processing of that first ring (to make an X11
Region) had a problem, therefore it had no X11 region to make a hole
in with the 2nd and succeeding rings.  That appears to be what it's
complaining about.

Thanks.
