  Trying to pair with my mobile phone kbluetooth4 keeps reporting an error. Just before the same phone has successfully been paired with bluetooth-wizard (gnome); initiating the pairing from the phone has also worked for KDE4. Beforehand re-pairing the old pairing has been removed on the phone as well as with kbluetooth4.

error message:
Sorry your bluetooth device does not support input service.
