Copied files to Extensions folder. Plugin is listed and starts. When clicking on "Anwenden", it seems to do something, but stops with following errors:

Can you provide the Inkscape file you used for testing? You could try to disable multi threading in the preferences since the traceback shows an error in the multi threading code.

631557fcd commented 2 years ago

Hello and thanks for the fast reply. The error happens on all files. If multi threading is disabled, it works. Which is good so far, but on more complex files it is very slow. I forgot to mention that i use Inkscape V1.1 on Kubuntu 20.04. Thanks for your work by the way!

I managed to reproduce this issue. Seems to be caused by missing x permissions on the temp share. For a quick test you could try sudo chmod 777 /dev/shm in the console. For a permanent solution check this thread: https://stackoverflow.com/questions/2009278/python-multiprocessing-permission-denied

Please let me know if that solved the issue for you.

Yes, this solves the problem. But as i am a bit paranoid, i think i stick with calculating on a single thread for safety reasons. Thanks again!
