561608 Debugging Python Dictionary Pickling Script

I have a python script which reads data from the internet, processes it, and then stores it in a dictionary. At the end of each cycle, the dictionary is the pickled. This program works fine however, every now and then, there is an issue when I try to open the dictionary backup. I get an EOFError error message. Upon awarding the bid, I can provide the programmer with the python script and a broken pickled dictionary.
