Application that crashed: kbluetooth4
Version of the application: 0.3
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.29.6-217.2.16.fc11.x86_64 x86_64

What I was doing when the application crashed:
On my Toshiba Portege R500, if I turn off bluetooth, kbluetooth4 crashes every time. Especially annoying since this machine turns bluetooth off while in suspend, so every wakeup it's the same crash. I suppose I could work around that case with a pm-utils script, but haven't tried it yet.
