Blender Version
Broken: 2.79 release 5bd8ac9

Importing a DXF file exported from QGIS fails with following exception.
Same DXF opens in Autodesk DWG TrueView 2018. It is a pretty simple map with a few areas.

Also, you can use "center geometry to scene" option and leave away "merge objects" option in your case.
