In Python, anytime you call "unbound" methods (i.e. by referencing
a class rather than an instance), you need to pass an instance -
in this case, self - explicitly.

For example:

    def manage_beforeDelete(self, item, container):
        CatalogAware.manage_beforeDelete(self, item, container)
        OrderedFolder.manage_beforeDelete(self, item, container)

But if your actual code looks like your example, you should have
gotten errors due to missing arguments.
