With qtcreator 3.2.0 build against Qt5, several shortcuts are broken when KDEPlatformTheme (frameworkintegration 5.1.0) is loaded. For example, when typing Alt+G, Alt+B (git blame), the Alt+G almost always triggers the "Go Back" button, and then Alt+B opens the build menu. The normal shortcut for the "Go Back" menu (Alt+Left) still works properly, and the Alt+G, Alt+B is correctly recognized in the settings (Options/Environment/Keyboard).
