QTabWibget удаление вкладки из стека QTabWidget

Всем доброго времени суток.
Что я делаю неправильно при удалении вкладки?

void MainTabWidget::on_MainTabWidget_tabCloseRequested(int index)
{
    removeTab(index);
    if(currentIndex() != -1){
        windowTitle = tr("Main window | ") + tabText(currentIndex());
    }else {
        windowTitle = tr("Main window");
        emit sendMenuToolsFlag(false);
    }
    emit sendWindowTitle(windowTitle);
    emit sendStatusBar(tabText(currentIndex()));
}

Но если я потом открою еще одну такую же вкладку (после удаления), то в стеке остается предыдущая, которая удаленная.
Вот так я создаю новую вкладку:

void MainTabWidget::actionOpenWrngObject()
{
    QString filename = QFileDialog::getOpenFileName(this, QString::fromUtf8("Open file"), QDir::currentPath(), "wiring data (*.xml *.XML *.Xml);;All files (*.*)");
    if(filename.isEmpty()){
        return;
    }
    QFileInfo fileInfo = filename;
    for (int ind = 0; ind < count(); ind++) {
        if(tabText(ind) == fileInfo.fileName()){
            setCurrentIndex(ind);
            return;
        }
    }
    objectwidget *newObjectWidgetPage = new objectwidget(this);
    newObjectWidgetPage->setWindowTitle(fileInfo.fileName());
    newObjectWidgetPage->setObjectName(fileInfo.fileName());
    newObjectWidgetPage->setFilename(filename);
    newObjectWidgetPage->import_data(&filename);
    if(!newObjectWidgetPage->error()){
        addTab(newObjectWidgetPage, newObjectWidgetPage->windowTitle());
        QString tabTitle = tr("Main window | ") +this->tabText(currentIndex());
        emit sendWindowTitle(tabTitle);
        emit sendStatusBar("Open file: " + filename);
        emit sendMenuToolsFlag(true);
        newObjectWidgetPage->add_actions(m_toolsActions);
        setCurrentWidget(newObjectWidgetPage);
        connect(this, SIGNAL(createNewWrngObject()), SLOT(show_selectDialog()));
        connect(this, SIGNAL(actionEditWrngObject()), newObjectWidgetPage, SLOT(action_edit()));
        connect(this, SIGNAL(actionDeleteWrngObject()), newObjectWidgetPage, SLOT(action_delete()));
    }else {
        newObjectWidgetPage->deleteLater();
        QMessageBox::critical(new QWidget(),tr("Error"),tr("The file is not valid!"));
        if(currentIndex() == -1){
            emit sendWindowTitle(tr("Main window"));
            return;
        }else {
            emit sendWindowTitle(tr("Main window | ") + tabText(currentIndex()));
            emit sendStatusBar(tabText(currentIndex()));
        }
    }
}

Заранее благодарю за помощь!
