Bug#894206: dxf2gcode: Traceback related to empty self.geo in polyline and lwpolyline

[Sebastian Kuzminsky]

Hi Sebastian, thanks for the bug report and the patches!  They look good 
to me at first glance, I will forward them upstream and if they agree 
I'll incorporate them into an updated debian package.

Do you have an example of a DXF file that fails before these patches and 
works after them?
