DataFrame#where broken in latest 0.16.1 release
Simple usecase of `DataFrame#where` fails on a freshly installed latest Pandas release:

```
In [1]: df = DataFrame([1, 2]); df
Out[1]: 
   0
0  1
1  2

In [2]: df.where(df[0]==1)
---------------------------------------------------------------------------
