Here I found that knotify4 was blocking in xine stuff; I sent a full multi-thread backtrace to Matthias Kretz.
Meanwhile it would be very nice if knotify4 being blocked, didn't block any application talking to it
via DBus (like kwin), so I suggested to Olivier Goffart to separate the phonon-using thread from
the dbus-request-handling thread in the knotify4 daemon. With a simple queue between both threads.

Because of those issue I haven't committed the knotify4-autostart patch yet...
(so right now it only autostarts via the dbus-1 mechanism, i.e. not for everyone)
