Hello. I've noticed a strange behavior of exclusive menu items. Take a look at the following sample:

Qt Code: 
  1. #include <QApplication>
  2. #include <QtGui>
  3. #include <QActionGroup>
  4.  
  5. int main(int argc, char* argv[])
  6. {
  7. 	QApplication app(argc, argv);
  8.  
  9. 	QMenu menu;
  10. 	QObject::connect(&menu, SIGNAL(aboutToHide()), &app, SLOT(quit()));
  11.  
  12. 	QActionGroup actionGroup(&menu);
  13. 	actionGroup.setExclusive(true);
  14.  
  15. 	for (int i = 0; i < 3; ++i)
  16. 	{
  17. 		QAction *action = actionGroup.addAction(QString("Action %1").arg(i));
  18. 		action->setCheckable(true);
  19. 		action->setChecked(i == 1);
  20. 	}
  21.  
  22. 	menu.addActions(actionGroup.actions());
  23. 	menu.show();
  24.  
  25. 	return app.exec();
  26. }
To copy to clipboard, switch view to plain text mode 

This works as expected and produces the following menu with exclusive item selection list:

Now I want to apply a very basic stylesheet to the menu, just to change a color. Here goes the qss script:
Qt Code: 
  2. {
  3. 	background-color: grey;
  4. 	color: #000000;
  5. }
To copy to clipboard, switch view to plain text mode 

Now apply the stylesheet (only 3 lines of code added):
Qt Code: 
  1. #include <QApplication>
  2. #include <QtGui>
  3. #include <QActionGroup>
  4.  
  5. int main(int argc, char* argv[])
  6. {
  7. 	QApplication app(argc, argv);
  8.  
  9. 	// apply stylesheet
  10. 	QFile qssFile(":/stylesheet/style.qss");
  11. 	qssFile.open(QIODevice::ReadOnly);
  12. 	app.setStyleSheet(qssFile.readAll());
  13.  
  14. 	QMenu menu;
  15. 	QObject::connect(&menu, SIGNAL(aboutToHide()), &app, SLOT(quit()));
  16.  
  17. 	QActionGroup actionGroup(&menu);
  18. 	actionGroup.setExclusive(true);
  19.  
  20. 	for (int i = 0; i < 3; ++i)
  21. 	{
  22. 		QAction *action = actionGroup.addAction(QString("Action %1").arg(i));
  23. 		action->setCheckable(true);
  24. 		action->setChecked(i == 1);
  25. 	}
  26.  
  27. 	menu.addActions(actionGroup.actions());
  28. 	menu.show();
  29.  
  30. 	return app.exec();
  31. }
To copy to clipboard, switch view to plain text mode 

Exclusive indicators are changed and look like non-exclusive:

Am I doing something wrong? How can this behavior be fixed?
