Bug 197371

Application that crashed: kbluetooth4
Version of the application: 0.3
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.30-8-generic i686
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
I run a Dell Latitude D630, this laptop has integrated bluetooth, and a way to turn off the antenna in hardware, whenever I do so, kdebluetooth4 crashes.

Steps to reproduce:
1) run kdebluetooth4.
2) turn off antenna.
