[Python] table.to_pandas segfault

[asfimport]

Here is a small snippet which produces a segfault:

In [1]: import pyarrow as pa

In [2]: import pyarrow.parquet as pq

In [3]: pa_ar = pa.array([[], []])

In [4]: pq.write_table(
   ...:     table=pa.Table.from_arrays([pa_ar],["test"]),
   ...:     where="test5.parquet",
   ...:     compression="snappy",
   ...:     flavor="spark"
   ...: )

In [5]: pq.read_table("test5.parquet")
Out[5]: 
pyarrow.Table
test: list<item: null>
  child 0, item: null

In [6]: pq.read_table("test5.parquet").to_pydict()
Out[6]: OrderedDict([(u'test', [None, None])])

In [7]: pq.read_table("test5.parquet").to_pandas()
Segmentation fault

I thank you in advance for having this fixed.

Best,

Jacques
