I have a shapefile consisting of linestrings, in which some of the features have null geometry. Yet, after importing it to PostGIS, using QGIS' DB Manager, a geometry is created for those features (what it does is create a small segment on top of another existing linestring).
Has anyone ever seen this happen? This problem doesn't happen when I import the shapefile using OpenGeo's pgShapeLoader. Is it a bug of DB Manager, or am I not configuring it correctly for importing?
I'm using QGIS 2.2.0 for mac, and PostGIS 10.1.0
