Bug#895862: dxf2gcode: Crashes "UnboundLocalError: local variable 'entities' referenced before assignment"

[Sebastian Kuzminsky]

Thanks for the bug report, and especially for the DXF file to reproduce 
it.  The DXF has no "entities" section, which is what caused the crash.

I've forwarded the bug report and the dxf to upstream, along with a 
patch that I believe fixes the problem.  I'll release a bugfix version 
of the debian package soon.
