I'm guessing that configuration and build_steps are supposed to be instance variables, not class-level variables. It would be interesting to see what your __init__ method looks like. I'm guessing you assign something the self.build_steps in __init__, but self.configuration is omitted. Try moving these initializers into the __init__ method, as: class subproject: def __init__(self): self.configuration = {} self.build_steps = [] and see if pickle starts behaving better. -- Paul -- http://mail.python.org/mailman/listinfo/python-list
