If you're deriving from BTree, make sure that the class BTree's __init__ method gets called.
Otherwise, there will be no BTree obeject to store your data in.

Does your class have an __init__ method? If so, you need to put as its first line:
  
  MyClass.inheritedAttribute('__init__')(self)

Where MyClass is the name of your class.
