Indeed, last time I worked with this data was before I upgraded to
gdal 3.02 (using the ppa https://qgis.org/ubuntugis/) and grass
7.8.3dev.

See attached a small sample (the original data is the BGT postgis dump
from https://nlextract.nl/downloads/), as well as a screenshot of the
data opened in QGIS and the same data imported in grass with v.in.ogr.
