Kuddi: XmlRpcClient error

Hi,
I'm start using KXmlRpc and I think that there is an error in 
XmlRpcClient, method execute

If the server don't exist or the port is closed an IOException is 
throwed and the catch print the exception .... but don't throw the exception

I put this code into the catch source :

.....

  } catch ( Exception x ) {
            x.printStackTrace ();
            result = x;   // throw the exception
        } finally {

.....
