I'm trying to use vegafusion in a Rust project. I'm using tokio to spawn a ipykernel (basically just using python -m ipykernel_launcher with the right flags), from within a virtualenv.
Now in that ipykernel, I have installed altair using vegafusion as a data-transformer. It all works well, except when it comes to a particular dataset. Vegafusion simply crashes when trying to do one of: chart.to_json(format="vega") or vf.save_vega(chart, file="spec.json") with this dataset.
It works with vegafusion with the exact same code when not using ipykernel
It works without vegafusion using ipykernel
fwiw, since #506 logs internal rust logs in my setup, I can see that the last thing it logs is:

Normally it goes on to show logs from the sql_optimizer, etc
