Description
Trying to read an MTK GML file which does not have any actual data, just container tags with python-ogr results in a NoneType object:
from osgeo import ogr ff = ogr.Open('/tmp/K23441.xml') type(ff) -> NoneType
The file in question is part of the official Finnish land survey database and can be downloaded e.g. here: http://kartat.kapsi.fi/files/maastotietokanta/kaikki/etrs89/gml/K2/K23/K23441_mtk.zip
This feature makes some conversion scripts (like ogr2osm) fail, so it would be nice to get an empty osgeo.ogr.DataSource object from empty containers, if possible.
Non-empty files work fine with the MTK GML driver, so thanks for that!
