Wrong number of row in to_latex output for MultiIndex Dataframe
If I try to run this code:

``` python

pd.DataFrame.from_dict({
    ('c1', 0): pd.Series({x: x for x in range(4)}),
    ('c1', 1): pd.Series({x: x+4 for x in range(4)}),    
    ('c2', 0): pd.Series({x: x for x in range(4)}),
    ('c2', 1): pd.Series({x: x+4 for x in range(4)}),
    ('c3', 0): pd.Series({x: x for x in range(4)}),
}).T.to_latex()
```

The result is 2 rows instead of 5 in the latex output. If I use a csv it works.

I'm running pandas 0.16.0 under python 2.7 on Mac OS X 10.10
