I'd start by looking for an attribute of pop that holds a reference to some function or method. E.g. something like this: class X(): def method(self): pass def __init__(self): self.L = [1, "a", X.method] # note the lack of ()s pop = X() Otherwise, I'm working blind without knowing more about your class. Here's a thought: comment out every attribute in your class, and then try pickling it. If it succeeds, uncomment just *one* attribute, and try pickling again. Repeat until pickling fails. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
