Probably the traceback constructor tried to iterate through the args.
You should initialize the args to an empty tuple, not None.  Also
note that there's an arbitrary number of them.  So you should probably
write:

 class nothing (exceptions.Exception):
     def __init__ (self, *args):
         self.args = args
 
You might also want to call Exception.__init__(*args) in the 
init func.
