error message [swig/python detected a memory leak of type 'EDA_ANGLE *', no destructor found.]

[Xeon-774]

This issue was created based on the discussion below,
In that discussion, it was suggested that the problem shown below was due to the kicad python API.
[https://github.com/yaqwsx/KiKit/discussions/673]
When I run the command provided by kikit to create a solder stencil, an error message is displayed.

command:
[kikit stencil createprinted --pcbthickness 1.6 --thickness 0.4 --framewidth 5.0 --ignore D1,R1 --frameclearance 0.3 --enlargeholes 0.1 ./3dprint_staincil_test.kicad_pcb ./staincil/]

error message:
[swig/python detected a memory leak of type 'EDA_ANGLE *', no destructor found.
swig/python detected a memory leak of type 'EDA_ANGLE *', no destructor found.]

The issue that was originally posted in the discussion, ``Stencil files are not generated correctly,'' has been resolved, but this error message still appears.

I have attached the pcb file that I used to verify the bug.
3dprint_staincil_test.zip

The environment used for verification was windows10, kicad 8.0.2, kikit1.5.1.

thank you.
