I use this library to navigate through a shape file containing a road network (made out of polylines). After the r.Next() call the function Shape() returns the row number -1. This results into endless loops and makes the library useless for any file reading. Are there already known situations this habit appeared? Do you have any solutions?
The road network has been created from a filtered OSM-file using QGIS.
