not sure but.. this bit reads really suspicious: while im is None: time.sleep(1) if im is ever None then how will it ever become not None? unless there is some other thread at work i can't really see this happening. and if there is some other thread at work then there is probably some better solution than sleep() -- https://mail.python.org/mailman/listinfo/python-list
