[BUG] DXF/Solvespace Export

[Jarshvor]

Describe the bug
I am unable to get DXF export to work (nor Solvespace export either).
I normaly run on Linux, but have also tested on Windows 10 and the symptoms appear to be the same.
On Linux Pyslvs-UI was installed via pip in a virtual-env (version 22.7.0), and on windows the "pyslvs-22.07.0.mscv1929-amd64.exe" was executed.

To Reproduce
Steps to reproduce the behavior:

1. Run Pyslvs-UI
2. Open 'File->Example->Arm'
3. Go to 'Proyect' Tab.
4. Click export DXF
5. Leave default options:
   • Export to folder with project name.
   • DXF vversion: AC1032 - R2018
   • Assembly
   • ... etc.
6. Click SAVE.
7. Pyslvs crashes.

Expected behavior
DXF (and Solvespace) Export to work, and not crash.

Desktop (please complete the following information):

• OS: [Arch Linux (6.5.8), Windows 10]
• Pyslvs Version: [22.7.0]

Additional context
Starting pyslvs with debug-mode (via pyslvs -d) gave no further info:
Aborted (core dumped).

P.S
Thank you for taking the time for sharing this great software.
I'm still learning it, but very happy it exists in the midst of the other not as open alternatives.

I've ran a backtrace of pyslvs from gdb and have uploaded the backtrace here:

Not sure how useful it is though, as I was not able to get py-bt working in gdb.
