pandas concat working in 0.12 but not 0.13 · Issue #5754 · pandas-dev/pandas (original) (raw)

I have a long list of dataframes that concat fine in 0.12 but not in 0.13. Has anyone seen this error?
I am concatenating using the following

pd.concat(all_gics, ignore_index=True) 

My traceback:

/usr/anaconda/lib/python2.7/site-packages/pandas/tools/merge.pyc in concat(objs, axis, join, join_axes, ignore_index, keys, levels, names, verify_integrity)
