i doubt this fix is correct. what looks more like is KStatusNotifierItemDBus::~KStatusNotifierItemDBus(). right now this is the implementation:

m_dbus.unregisterService(m_service);

and perhaps it should include:

m_dbus.unregisterObject("/StatusNotifierItem", this);

and perhaps even:

m_dbus.disconnectFromBus(m_service);

(though i expect the latter is done automatically when QDBusConnection is deleted? maybe not though...)


kdeui/notifications/kstatusnotifieritem.cpp
<http://git.reviewboard.kde.org/r/101527/#comment3080>

    statusNotifierItemDBus is initialized this way:
    
    statusNotifierItemDBus = new KStatusNotifierItemDBus(q);
    
    where 'q' is the QObject-derived StatusNotifierItem. and here is the constructor:
    
    KStatusNotifierItemDBus::KStatusNotifierItemDBus(KStatusNotifierItem *parent)
      : QObject(parent),
    
    
    so i'd be very surprised if it wasn't being deleted when KStatusNotifierItem is deleted. can you confirm that it is not being deleted by putting some debug output in ~KStatusNotifierItemDBus?
