Try opening the file in universal newline mode:

f = open("my.pickle", "U")
print pickle.load(f)

This will convert Windows "\r\n" line endings to "\n".

For new data: an alternative is to open the file in binary mode for both 
reading and writing on all platforms. This will also allow you to switch to 
the more efficient binary pickle protocols.
