Failed to create the output layer: non riesco a creare il layer (errore
OGR:Geometry type of `Unrecognised: 1003' not supported in shapefiles.
Type can be overridden with a layer creation option
Note from Even Rouault:
Sounds like a PolygonZ (=1003) is passed to OGR as WKB encoded with ISO
SQL/MM to GDAL 1.11 or older. Only GDAL 2.0 will support that. GDAL 1.X
will only support old-style 99-402 extended dimension (Z) WKB, so
Polygon25D = 0x80000003
Thanks Even. In this case, the plugin would be essentially broken in all
systems with gdal<2 (as in Debian sid9), right?
Yes, it seems than any 3D geometry outputted by this plugin will not be GDAL
1.X compatible. 2D geometries should be OK though.
Perhaps there's somewhere in QGIS code base a way of converting ISO WKB to
old-style WKB ?

The geometry checker plugin simply clones the layer using QgsVectorFileWriter before it starts processing it. So QgsVectorFileWriter needs to be adapted to handle 3D geometries. The geometry checker plugin itself should not really care about whether a geometry is 2D or 3D.
