Now this is strange. I cannot reproduce it on my system. When switching to 'show the menus for a window: In the menu bar' with my appmenu-qt5 installed and latest Qt5.2.1 from the archives, I get the test application you have provided working as expected. I can see both the icons on the toolbar and in the menu entries.
Could you give me some more info about the system you are running? What Qt versions are you using, what is the currently installed appmenu-qt5? Is it a freshly installed system, or after an upgrade?
