There shouldn't be any changes at all happening to any of the pickling 
machinery... A 'StringO' object is what you get when you use 
cStringIO.StringIO. Is your product using cStringIO for anything? If 
not, it would be best to trace this in the debugger to see what is 
trying to pickle a StringO...
