When Qt is building an application on OSX, it is imitating the behaviour of the native OSX menu structure by creating a menu entry with the program name - right? When I add an action to the menu with the name "About" or "Preferences", then these entries are entering automatically into this program name drop down menu. This behavior is working in Qt 4.8 but not working with Qt 5.1. I guess it is a bug in 5.1, or was decided to change the behavior?
For testing purposes, I also added a small example which is working on 4.8
and on 5.1 with the descriped behavior.
