Trying to write a zero-RecordBatch file to parquet:

{code:python}
import pyarrow
import pyarrow.parquet
table = pyarrow.Table.from_batches([], pyarrow.schema([('A', pyarrow.dictionary(pyarrow.int32(), pyarrow.string()))]))
pyarrow.parquet.write_table(table, 'x.parquet')
{code}

... I receive an error and Python exits with exit code {{139}}:
