I recognized a similar error with amarok starting the second time. I had 
to restart dbus-daemon to avoid this message. In that case i assume that 
the service KUniqueApplication registers in dbus wasn't unregistered at 
application shutdown. At least there is no unregisterService() call in 
whole kdelibs.  May be that thiago can give some lights in this area. 
Anyway the related code is located in 
kdelibs/kdeui/kernel/kuniqueapplication.cpp line 146

bool
KUniqueApplication::start()


     // Check to make sure that we're actually able to register with the 
D-Bus session
     // server.
     if (dbusService->registerService(appName) != 
QDBusConnectionInterface::ServiceRegistered)
     {
        kError() << "KUniqueApplication: Can't setup D-Bus service. 
Probably already running."
                 << endl;
        ::exit(255);
     }
