Surely the above should be:
      a.manage_addProperty('apple_type',a.get_apple_type(),'select')

well, I reckon that may have been 'cos you actually ended up adding the 
get_apple_type method object as an attribute of your apple rather than the 
result of calling that method (see my added brackets in the above code).

Method objects aren't pickleable, which hopefully explains your error.
