It's not difficult to add support for sending an error from setter or a 
getter, the same way that it's done for a normal method. It's not via C++ 
exceptions, but with a call to QDBusContext::sendError().

But from the client side, there's no way to determine if a setting failed 
(QObject::setProperty returns void) or the reason why a get failed. If an 
API required checking those, the client would have to call the Get and 
Set methods directly.
