Bug#950924: python-feather-format: FTBFS with pandas 1.0: test_boolean_object_nulls / test_sparse_dataframe fail

[Rebecca N. Palmer]

The patch still works for me (on amd64, dpkg-buildpackage in a chroot 
with experimental python3-pandas(-lib), sid everything else; keep the 
existing pandas025.patch).  Anything obviously different about your test 
environment?
