python-mode problem, doesnt load whole module?

[cnb]

>>> a = parsing.unserialize("C:/users/saftarn/desktop/twok.txt")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python25\Progs\NetflixRecSys\parsing.py", line 91, in
unserialize
    return pickle.load(open(filename, 'r'))
  File "C:\Python25\lib\pickle.py", line 1370, in load
    return Unpickler(file).load()
  File "C:\Python25\lib\pickle.py", line 858, in load
    dispatch[key](self)
  File "C:\Python25\lib\pickle.py", line 1090, in load_global
    klass = self.find_class(module, name)
  File "C:\Python25\lib\pickle.py", line 1126, in find_class
    klass = getattr(mod, name)


if i use the python-gui-editor-repl it works though...

so isn't emacs loading modules properly? this shouldnt have to do with
emacs itself though, right?
