bluetooth doesn't work in kde intrepid

[Pascal d'Hermilly]

Binary package hint: kdebluetooth

I'm not able to use the kde4 bluetooth tools anymore. It still works with the gnome-applet though.
It used to work.

using fully up to date Intrepid.

This is normally a bug in some application using the D-Bus library.
