thanks for the dxf file. I see that the version number $ACADVER is AC1006. This means that it is Release 10. The current dxf import routine supports only Release 13 and newer. Release 10 contains entities such as POLYLINE and VERTEX which are no longer supported.
If necessary, it is possible to upgrade the dxf file to a newer version. Open it in QCad and then save it using the default file type DXF. This will automatically convert it to Release 13 or newer. The result is attached here, and is viewable in Inkscape.
