when testing new GFS files for GML driver I found possible bug in the driver.
Program received signal SIGSEGV, Segmentation fault.

In this case `nIdx = 1` and `m_nGeometryCount = 0`. The features in
this layer have one or two geometry colums.
<obi:Geometrie>
<obi:DefinicniBod>
<obi:OriginalniHranice>
</obi:Geometrie>
'DefinicniBod' can be Point or MultiPoint, OriginalniHranice is
MultiSurface (so MultiPolygon). The driver fails when 'Geometrie'
contains only 'OriginalniHranice'. The relevant part of GFS file:
<GeomPropertyDefn>
<Name>DefinicniBod</Name>
<ElementPath>Geometrie|DefinicniBod</ElementPath>
<Type>MultiPoint</Type>
</GeomPropertyDefn>
<GeomPropertyDefn>
<Name>OriginalniHranice</Name>
<ElementPath>Geometrie|OriginalniHranice</ElementPath>
<Type>MultiPolygon</Type>
</GeomPropertyDefn>
I will prepare sample test file later tomorrow, Martin
