PyQt - Set model of a proxymodel in QThread

In my project i noticed that the main dialog freezes when it is setting the model of some ProxyModel, so i decided to create a new thread for this task to provide the responsiveness of the window, but right now it keeps popping an error that say:
TypeError: QTableView.setModel(QAbstractItemModel): argument 1 has unexpected type 'tuple'

and i don't know why...
Here's my code:

This is the QThread for updating the proxyModel with the arguments i provide 

class ThreadedProxyModel(QThread):
    def __init__(self, contacts, contactsProxyModel, groups, groupsProxyModel,
                 chatSession, chatSessionProxyModel, msgs, msgsProxyModel):
        QThread.__init__(self)
        self.contacts = contacts
        self.contactsProxyModel = contactsProxyModel
        self.groups = groups
        self.groupsProxyModel = groupsProxyModel
        self.chatSession = chatSession
        self.chatSessionProxyModel = chatSessionProxyModel
        self.msgs = msgs
        self.msgsProxyModel = msgsProxyModel

    def run(self):
        self.contactsProxyModel.setSourceModel(recordsTableModel(self.contacts))
        self.contactsProxyModel.setFilterKeyColumn(-1)
        self.contactsProxyModel.setFilterCaseSensitivity(Qt.CaseInsensitive)

        self.groupsProxyModel.setSourceModel(recordsTableModel(self.groups))
        self.groupsProxyModel.setFilterKeyColumn(-1)
        self.groupsProxyModel.setFilterCaseSensitivity(Qt.CaseInsensitive)

        self.chatSessionProxyModel.setSourceModel(recordsTableModel(self.chatSession))
        self.chatSessionProxyModel.setFilterKeyColumn(-1)
        self.chatSessionProxyModel.setFilterCaseSensitivity(Qt.CaseInsensitive)

        self.msgsProxyModel.setSourceModel(recordsTableModel(self.msgs))
        self.msgsProxyModel.setFilterKeyColumn(-1)
        self.msgsProxyModel.setFilterCaseSensitivity(Qt.CaseInsensitive)

    def getContactsProxyModel(self):
        return self.contactsProxyModel,

    def getGroupsProxyModel(self):
        return self.groupsProxyModel

    def getChatSessionProxyModel(self):
        return self.chatSessionProxyModel

    def getMsgsProxyModel(self):
        return self.msgsProxyModel

And this is the method calling the setProxyModel thread in the dialog class. Notice that all the data (contacts, groups, chatsession...) is fine:

def setProxyModel(self):
    progress = QProgressDialog("Initializing UI ...", "Abort", 0, 0, self)
    progress.setWindowTitle("WhatsApp Browser ...")
    progress.setWindowModality(Qt.WindowModal)
    progress.setMinimumDuration(0)
    progress.setCancelButton(None)
    progress.show()

    queryTh = ThreadedProxyModel(self.contacts, self.contactsProxyModel, self.groups, self.groupsProxyModel,
                                 self.chatSession, self.chatSessionProxyModel, self.msgs, self.msgsProxyModel,)
    queryTh.start()
    while queryTh.isRunning():
        QApplication.processEvents()

    self.contactsProxyModel = queryTh.getContactsProxyModel()
    self.groupsProxyModel = queryTh.getGroupsProxyModel()
    self.chatSessionProxyModel = queryTh.getChatSessionProxyModel()
    self.msgsProxyModel = queryTh.getMsgsProxyModel()

    progress.close()

And this is in the init method in my dialog, i create the proxymodels and call the method for updating them in the Thread and then i set them up in various QTableView:

self.contactsProxyModel = QSortFilterProxyModel(self)
self.groupsProxyModel = QSortFilterProxyModel(self)
self.groupMembersProxyModel = QSortFilterProxyModel(self)
self.chatSessionProxyModel = QSortFilterProxyModel(self)
self.chatMsgsProxyModel = QSortFilterProxyModel(self)
self.msgsProxyModel = QSortFilterProxyModel(self)

self.setProxyModel()

self.contactsTableView.setModel(self.contactsProxyModel)
self.contactsTableView.resizeColumnsToContents()

self.groupsTableView.setModel(self.groupsProxyModel)
self.groupsTableView.resizeColumnsToContents()

self.chatSessionTableView.setModel(self.chatSessionProxyModel)
self.chatSessionTableView.resizeColumnsToContents()

self.chatSessionTableView.clicked.connect(self.setChatMsgsProxyModel)
self.chatMsgsTableView.resizeColumnsToContents()

self.groupsTableView.clicked.connect(self.setGroupMembersProxyModel)
self.groupMembersTableView.resizeColumnsToContents()

self.msgsTableView.setModel(self.msgsProxyModel)
self.msgsTableView.resizeColumnsToContents()

Thank you for any advice, i'm pretty stuck...

Not sure, but it seems that 

def getContactsProxyModel(self):
   return self.contactsProxyModel,

return a tuple, try to delete the comma
