strange error with Pandas-0.19.0 
Just to raise eyebrows, not sure if it's related to pandas-0.19 or to a bug of myself.
It is ok under Pandas-0.18.1 (and seems not related to Python-3.6)

#### A small, complete example of the issue

```python
# in Ipython
#Pandas 
import pandas as pd
import numpy as np

idx = pd.date_range('2000', '2005', freq='d', closed='left')
datas = pd.DataFrame({'Color':  [ 'green' if x> 1 else 'red' for x in np.random.randn(len(idx))], 
         'Measure': np.random.randn(len(idx)), 'Year': idx.year},
          index=idx)
#datas.head()
# checking baresql
from __future__ import print_function, unicode_literals, division  # line needed only if Python2.7
from baresql import baresql
bsql = baresql.baresql(connection="sqlite:///.baresql.db")
bsqldf = lambda q: bsql.df(q, dict(globals(),**locals()))

bsqldf("select Color, Year from datas$$") 
```

#### Expected Output
this:
![pandas-0 19](https://cloud.githubusercontent.com/assets/4312421/19895656/e6372b0a-a051-11e6-924a-2bd034fc446c.PNG)
