Reading the code, there appears to be some sort of support for it by
appending a suffix like "_p" to the typename to get only points.
Unfortunately this does not lead to a specific geometry attribute type.
It's a bit of a kludge to be honest.

Thank you for the help Matthijs.
Can I filter only points, then lines and so on?

Where Geometry is an abstract class! For that I'm wondering why I
have the fault (shapefiles don't generate it). It seems I have a not
recognized GeometryDescriptor created by the DXF Plugin.
What do you think about?
The reason for a generic Geometry attribute is that a dxf file does
not contain a single geomtry type such as lines or polygons.
So when you read features from the dxf datastore you can get all of
points, lines and polygons mixed together, unlike shapefiles which
are only of a single geometry type. Apparently the code you are using
always assumes a single geometry type.
