DataFrame.from_dict (orient broken?)
I tried creating using the from_dict() method to create a dataframe recently and noticed that orient='index' failed, even with trivial data.

It also failed with tuple values in the dictionary.

My current workaround is just to take the dataframe and perform a transpose, no big deal really.
