Malformed dict created from squeezed dataframe
[error_dict.txt](https://github.com/pandas-dev/pandas/files/2948709/error_dict.txt)

```python
Python 3.6.7 (default, Oct 22 2018, 11:32:17) 
[GCC 8.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>> error_dict = pd.read_csv("error_dict.txt")   #github doesn't support attach csv
>>> dict(error_dict.set_index('FIELD').squeeze())

```

This outputs a malformed dict:
