So far I did not manage to start a KDE3 program inside my KDE4 session (some 
auth problems I need to understand) but it looks that it isn't KMenuBar which 
is broken. Some other toplevel windows are also not signalled, e.g. a ripped 
of toolbar. No windowAdded() signal emitted, still both menubar and toolbar 
are window system items with their id and properties like:
Menubar:
_NET_WM_WINDOW_TYPE(ATOM) = _KDE_NET_WM_WINDOW_TYPE_TOPMENU, 
_NET_WM_WINDOW_TYPE_UTILITY
Toolbar:
_NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_UTILITY, 
_KDE_NET_WM_WINDOW_TYPE_OVERRIDE, _NET_WM_WINDOW_TYPE_NORMAL

Interestingly enough if I click on/activate the toolbar KWindowSystem emits 
the signal activeWindowChanged(). Any idea where I should look for now?
