    Description

      QTabWidget::removeTab removes 2 tabs (instead of 1) in almost all cases. Only when the last tab is removed, the function works correct and only 1 tab is removed.

      For example:

       

      QTabWidget* pTabWidget = new QTabWidget();
pTabWidget->addTab(new QWidget(), "1");
pTabWidget->addTab(new QWidget(), "2");
pTabWidget->addTab(new QWidget(), "3");
pTabWidget->addTab(new QWidget(), "4");

delete pTabWidget->widget(1);
pTabWidget->removeTab(1); //This removes tab "2" and "3", which is incorrect
delete pTabWidget->widget(pTabWidget->count() - 1);
pTabWidget->removeTab(pTabWidget->count() - 1); //This removes only tab "4", which is correct
