I could reproduce the error message with the small test suite
embedded at the end of the SmoothMeshLines.py file, using the
command:

	$ python3 /usr/lib/python3/dist-packages/CSXCAD/SmoothMeshLines.py

I can confirm this helps with the small test.  By appending your
fix, I could spawn the expected window with the line instead of
the crash.  This shouldn't bring regressions in other areas
hopefully.  I'm preparing a patch and will upload soon.

Thanks for your report!
Have a nice day,  :)
