This bug also affects tray (appindicator) menu items. With
env UBUNTU_MENUPROXY=''
the shortcuts work, but not the tray menu, also problems with updating the tray icon. With
env QT_QPA_PLATFORMTHEME=''
everything works, but the UI degrades considerably (no Unity look&feel). Same behavior when removing appmenu-qt5 (everything works, degraded UI).
