AttributeError: Обектът „NoneType“ няма атрибут „userprofile“

Продължавам да получавам тази грешка и някак съм заседнал. Знам, че има нещо общо с последната част от кода, но освен това съм най-вече объркан и не съм много сигурен как да го поправя/изпълня корекции.

Разделът, който извиква панел (част от меню с визуални опции):

    self.AutojoinMemosPanel = GUI.Options.Panels.AutojoinMemos.Panel(self.config,self)
    self.pages.addWidget(self.AutojoinMemosPanel)

Панел:

class MemoEntryItem(QtGui.QListWidgetItem):
def __init__(self,MemoName):
    QtGui.QListWidgetItem.__init__(self,MemoName)
    self.MemoName = MemoName

    QtGui.QWidget.__init__(self)
    self.Config = Config

    self.AutoIdentifyCheck = QtGui.QCheckBox("Automatically identify with nickserv")
    self.PasswordLabel = QtGui.QLabel("Password:")
    self.PasswordEntry = QtGui.QLineEdit()
    self.PasswordEntry.setEchoMode(QtGui.QLineEdit.Password)

    self.TitleLabel = QtGui.QLabel("Memos to join on startup:")
    self.MemosList = QtGui.QListWidget()

@QtCore.pyqtSlot()

    if (MemoName != ""):
        self.AddMemoEntry(MemoName)
        self.MemoNameEntry.setText("")

def AddMemoEntry(self,MemoName):
    self.MemosList.addItem(MemoEntryItem(MemoName))

def SaveOptions(self):
    MemosListed = []

    for MemoIndex in range(self.MemosList.count()):
        MemoItem = self.MemosList.item(MemoIndex)
        MemosListed.append(MemoItem.MemoName)

    self.Config.set("AutojoinMemos",MemosListed)

    self.Config.userprofile.userprofile["AutoIdentify"] = self.AutoIdentifyCheck.isChecked()
    self.Config.userprofile.userprofile["NickservPassword"] = str(self.PasswordEntry.text())

Някаква помощ?
