as the name implies, "args" is supposed to be a sequence, and is stored 
internally as a tuple.  if something has changed, it's probably that 2.5 
enforces this behaviour via a property.

to fix your code, just replace your own __init__ method with a "pass", 
and leave the initialization to the Exception class itself.
