ParserError on read_table/read_csv while reading CSV file
#### Code Sample, a copy-pastable example if possible

```python
In [137]: probes = pd.read_csv('example_pandas.csv', sep=',', index_col=0)

```
#### Problem description

I am getting this ParserError while trying to load a CSV file. I prepared a minimal example to reproduce this error.

[example_pandas.csv.zip](https://github.com/pandas-dev/pandas/files/1969094/example_pandas.csv.zip)

 I have the latest version of Pandas on macOS 10.13.2 (17C205) - High Sierra.

I checked the example and it seems the CSV has the correct format, but maybe the problem is in the CSV itself.

#### Expected Output

The expected output should be a dataframe with only one column (the first CSV column is used as index).

#### Output of ``pd.show_versions()``
