Issue description
This is in fact a Rust issue, introduced in version 0.40.0. (pola-rs/r-polars#1104 (comment))
I mistakenly thought this was an R bindings issue that did not occur in Python at first, but in fact it also occurs in Python when collecting LazyFrames.
Expected behavior
Should not panic.
