Cannot save to dxf, script error occured

[Yann Papouin]

I've attached the svg file that need to be saved as dxf.

This is the output:

Traceback (most recent call last):
  File "dxf_outlines.py", line 299, in <module>

From the attached file:
   inkscape:version="0.48+devel r11093"

Reproduced with Inkscape 0.48+devel r11093 on OS X Lion:

AFAICT the python script fails to handle orphaned clones: it crashes instead of ignoring them (simple test case attached).

[su_v (suv-lp)]

A "regular" clone exports ok for me.

[su_v (suv-lp)]

Attaching "fixed" version of the original sample file which exports to DXF without python failure (all orphaned clones deleted, some of the inside otherwise empty groups).

thanks for testing, attached is a slightly modified version of dxf_outlines.py. This will silently ignore the orphaned clones.

Thanks both of you for this quick fix, it saves my week :)

I also need to save only one layer, so I made a proposal based on your work:
