Hello,
The simple example works fine using __reduce__:
class MyError(Exception):
def __init__(self, arg):
self.arg = arg
def __reduce__(self):
return (MyError, (self.arg, ))

Here is my example :
import cPickle
ParentClass = object # works
ParentClass = Exception # does not
class MyError(ParentClass):
def __init__(self, arg):
self.arg = arg
def __getstate__(self):
print '#DBG pass in getstate'
odict = self.__dict__.copy()
