Memory error when plotting simple time series

[andreabedini]

This crashes:

import pandas as pd
index = pd.timedelta_range(start="06:00:01", end="12:00:00", freq='S')
pd.Series(range(index.size), index=index).plot()

So far I have figured out that _get_default_locs gets called with completely bogus vmin an vmax.
