ValueError: Expecting object from python 2.7.1 on Mac OS X

Tried to follow the steps from http://www.howtogeek.com/162106/how-to-export-your-starred-items-from-google-reader/ but I'm seeing the following error:

Lees-MacBook-Pro:Reader lee$ python ./export2HTMLFiles.py
Traceback (most recent call last):

ValueError: Expecting object: line 28695 column 3 (char 6444831)

Start with export2HTMLFiles.py at line 59 and reproduce the reported Python 2.7 command on the supplied export data. Inspect the JSON around line 28695, column 3, to determine why parsing stops there; done means the script parses the data and completes its export without this ValueError.
