Not sure if this is relevant, but here are my findings

I **removed** all dbus files except dbus.dll and launched konversation. Upon
exit it hanged on QDBusServiceWatcher destructor.

        Qt5Cored.dll!QWaitConditionPrivate::wait(QWaitConditionEvent * wce,
unsigned long time) Line 119        C++
        Qt5Cored.dll!QWaitCondition::wait(QMutex * mutex, unsigned long time)
Line 184  C++
        Qt5Cored.dll!QSemaphore::acquire(int n) Line 143        C++
        Qt5Cored.dll!QMetaObject::activate(QObject * sender, int signalOffset,
int local_signal_index, void * * argv) Line 3709 C++
        Qt5Cored.dll!QMetaObject::activate(QObject * sender, const QMetaObject

        KF5Notifications.dll!KNotificationManager::~KNotificationManager() Line

If there is no dbus daemon running, the watcher clearly shouldn't hang on
waiting something, am I right?
