Since you "don't use a dictionary anymore" you have presumably changed
the WSDL.  Have you re-generated the interfaces (using tools/GenerateInterfaces.py)
since you changed the WSDL to not use dictionaries?  If so, I would check
in AccessGrid/interfaces/AccessGrid_Types.py to see how DirectoryDescription
is represented.
