Polars Plugin segfault MCVE

There's a really small Polars plugin which sometimes segfaults.

How to reproduce:

• cd polars-business
• make venv
• make install
• pytest (run this one a few times)

This doesn't always segfault, just sometimes.

I just ran pytest 10 times, and it passed 4 times and segfaulted 6 times.

If I apply the following diff:

diff --git a/polars_business/polars_business/polars_business/__init__.py b/polars_business/polars_business/polars_business/__init__.py
index ebd9bbfaf..89b8c02b0 100644

             kwargs={

then pytest always passes.
