I have worked on a fix for this yesterday, or to be more precise on two fixes.
Fix for appmenu-qt5: lp:~mitya57/appmenu-qt5/lp1574699 Fix for pure Qt without appmenu-qt5: https://codereview.qt-project.org/158963
As you seem to be using Unity, you are probably also using appmenu-qt5. So marking this bug as duplicate of bug 1574699 which is reported against right project.
