Hi,
I have the problem that Spyder crashes when I try do display a Pandas DataFrame in the Spyder variable explorer. The problem only occurs, if there are duplicate columns in the DataFrame. Example:

2015-06-17 15_50_05-spyder python 2 7

Now, double clicking on the variable "new_df" in the variable explorer leads to a crash of Spyder.

My software versions are:

Sypder 2.3.4
Pandas 0.16.2
Iphyton 3.1.0

Best regards

A simpler example to test

import pandas as pd
df = pd.DataFrame([[1,2],[3,4],[5,6]], columns=['a','a'])

Backport (and improve) fix for issue #2491

- Use iloc to get DataFrame values under *all* possible errors
- This avoids Spyder to crash if different errors than the ones
previously considered are generated by iat
