Comment 16 for bug 1375196

Had you been able to fix the reported issue by restoring all files which possibly got replaced by when installing custom output extensions "Better DXF output" or "Big Blue Saw" on the affected computers?

[ IIRC at least one of these custom and outdated DXF output extension also overwrites one of the shared python modules shipped with Inkscape (used by other extensions too) with a modified version based on a much older Inkscape release. ]
