Addon Information

Author: Remigiusz Fiedler (AKA migius), Vaclav Klecanda

Short description of error
If an object has a material slot but no material assigned to it, then DXF export fails with an error message in system console:

Nothing exported. Error: 'NoneType' object has no attribute 'diffuse_color'

When exporting multiple objects, if at least one object has an empty material slot, whole export fails and no .dxf file is written.

Exact steps for others to reproduce the error

Open attached .blend file or
- Open default Blender scene
- Select the cube and go to Material Properties tab
- Unlink the default material
Export as DXF
See console

Thanks for the report. Can not reproduce on current master.
Can you provide broken .dxf file?

There is no broken .dxf file because this is an issue with exporting. If export fails, .dxf file is not created.
I can only provide .blend file that is set up in a way that causes the error.
