Right, with QApplication QtDbus doesn't get loaded and everything
works, with KApplication QtDbus does get loaded and it freezes if
using python-dbus with the Qt mainloop (setting set_as_default=False
makes it use the glib mainloop, no freeze but you won't get any dbus
signals either).

Trolltech tell me they can't recreate it in Qt 4.4 RC 1 so maybe this
has been magically fixed, we should find out tomorrow.
