I searched for qplatforminputcontext and dbus related commits in 5.3.x, but none seemed to touch the places in code where the trace points to. But in doing that, I figured out that while QDBus is in qtbase, "MInputContext" is not in platforminputcontext (in qtbase) where I thought it'd be, but instead it's in maliit-framework.
