Application that crashed: kbluetooth4
Version of the application: 0.3
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
When resuming from Suspend KBluetooth crashes with a segmentation fault. The bug also happens (with the same backtrace) when having kbluetooth4 running and doing an "/etc/init.d/bluetooth stop".

 -- Backtrace:
Application: KBluetooth4 - The KDE4 Bluetooth Framework (kbluetooth4), signal: Segmentation fault
