ion-elgreco opened a new issue, #7549:
URL: https://github.com/apache/arrow-rs/issues/7549

   **Describe the bug**
   Can't consume arrow data with empty list[str] over FFI
   
   
   **To Reproduce**
   ```python
   import polars as pl
   from arro3.core import Table
   df = pl.DataFrame(
       {
           "bar": [[]],
       }, schema={"bar": pl.List(pl.String)}
   )
   
   Table(df)
   ```
   
   **Expected behavior**
   Pyarrow seems to be able to consume this empty list[str] fine,
   
   ```python
   import polars as pl
   import pyarrow as pa
   df = pl.DataFrame(
       {
           "bar": [[]],
       }, schema={"bar": pl.List(pl.String)}
   )
   
   pa.table(df)
   ```
   
   **Additional context**
   Created also issue in polars repo: 
https://github.com/pola-rs/polars/issues/22935, since it's not clear to me 
where the issue lies, wether it's polars buffers being misaligned or arrow-rs 
incorrectly identifying it because pyarrow seems to be able to consume it fine.
