Comment 85 for bug 280997

KDE 4.1.96-0ubuntu1~intrepid1~ppa1
kdebluetooth 0.3-1ubuntu0.1
kdebase-workspace 4.1.96-0ubuntu4~intrepid1~ppa1
bluez 4.25-0ubuntu1~git20081226

I deleted all devices using gnomes "bluetooth-applet" in a terminal and then closed the terminal stopping the applet
Then I ran kbluetooth4-devicemanager in a terminal
in "select your device" I selected my BT mouse and clicked next, the device manager crashes with the following output

The mouse still appeared to be in discovery mode.
I disconnected the batteries to my mouse and reconnected it.
It then paired with my laptop OK.
I then re-ran kbluetooth-devicemanager in a new terminal and got the following output

paulo@illustrious:~$ /usr/bin/kbluetooth4-devicemanager

kbluetooth4-devicemanager no longer runs
I then configured the mouse with Gnomes "bluetooth-applet" as above and closed the terminal
Then I retried kbluetooth4-devicemanager but it won't run with the following output which appears identical to the above output apart from the numbers

Hope this helps
