index = pd.Index(range(3)).repeat(2)

>>> index.drop(1)
Traceback (most recent call last):
[...]
pandas.errors.InvalidIndexError: Reindexing only valid with uniquely valued Index objects

It is using Index.get_indexer, which is only for uniques indexes.

Got another Problem with duplicates in MultiIndex

mi = MultiIndex.from_tuples([(1, 2), (2, 3), (1, 2)])
print(mi.drop((1, 2)))

returns an empy MultiIndex
