test_range_slice_outofbounds 
Sorry to be the error guy - but all variations now giving:

```
======================================================================
ERROR: test_range_slice_outofbounds (pandas.tseries.tests.test_period.TestPeriodIndex)
----------------------------------------------------------------------
Traceback (most recent call last):

  File "hashtable.pyx", line 381, in pandas.hashtable.Int64HashTable.get_item (pandas/hashtable.c:7008)
TypeError: an integer is required
```

With continuing stream of KeyError errors.  ?Data changed upstream somewhere?
