I exported a DXF from QGIS by right-clicking on the layer. Then tried to open in AutoCAD 2000.
That did not work. AutoCAD gave a failure-message:
Unknown Value "AC1018" found in drawingversion.
Then I tried to view the file in DWG-Truview2013 – which didn't work either giving the following error:
Invalid database handle 0 on line 1548.
Invalid or incomplete DXF input -- drawing discarded.
Does anyone know a solution? Or is there anywhere in QGIS change the DXF-Version to export?

Given that your autocad version is 12+ years old it may be an issue with autocad dwg or dxf file format version (major format version: http://en.wikipedia.org/wiki/.dwg#Version_history). You should try to open it in a newer version of ACAD, or try saving it into an older format.
