error in to_pickle

I think there is a bug in to_pickle
>>> data = pd.read_hdf(DG.load_path + 'time_series/PSI_TS_after_alignment_and_reshaping.h5', 'table')
>>> data.shape

>>> data.to_pickle(DG.load_path + 'time_series/PSI_TS_after_alignment_and_reshaping2.pkl')
Traceback (most recent call last):
