+Subject: [PATCH] QtDBus: clean up signal hooks and object tree in
+ closeConnection
+
+If a QObject is added or passed as receiver to QDBusConnection::connect()
+and it is managed by Q_GLOBAL_STATIC or similar mechanism, it is
+possible that when that its destructor is called after the dbus daemon
+thread ends. In that case, QObject::destroyed connected via
+Qt::BlockingQueuedConnection to QDBusConnectionPrivate will cause dead
+lock since the thread is no longer processing events.
+
+Task-number: QTBUG-51648
+Change-Id: I1a1810a6d6d0234af0269d5f3fc1f54101bf1547
