BUG: tuple as index not possible anymore in pandas 0.14?
I used to do convert a dict with tuple keys to DataFrame like

```
DataFrame.from_dict(a_dict, 'index')
```

but it produces "IndexError: index out of bounds" from pandas 0.14.  Is there a way that I still can use tuple as Dataframe label?  My old codes do not work with 0.14.
