Package: gdal-bin

$ ogrlineref -create -l zk1.kml -p zk0.kml -pm emds -o parts.kml -s 222
Warning: The target file has a 'kml' extension, which is normally used by the KML/LIBKML driver,
but the requested output driver is ESRI Shapefile. Is it really what you want ?
Makefile:8: recipe for target 'p' failed
make: *** [p] Segmentation fault

OK, but there is no need to cause Segmentation fault.
