Volker,
It's windbus 1.1.2. We're rather well aware of the risk of using global 
objects, so we use K_GLOBAL_STATIC and qAddPostRoutine. I am attaching current 
example from kdelibs/interfaces/ktexteditor.cpp, in case I have misunderstood 
something:

struct KTextEditorFactoryList : public QList<KPluginFactory*>
{
   KTextEditorFactoryList();
   ~KTextEditorFactoryList();
};
K_GLOBAL_STATIC(KTextEditorFactoryList, s_factoryList)
KTextEditorFactoryList::KTextEditorFactoryList() {
   // K_GLOBAL_STATIC is cleaned up *after* Q(Core)Application is gone
   // but we have to cleanup before -> use qAddPostRoutine
   qAddPostRoutine(s_factoryList.destroy);
}
KTextEditorFactoryList::~KTextEditorFactoryList() {
   qRemovePostRoutine(s_factoryList.destroy); // post routine is installed!
   qDeleteAll(*this);
}
