Application: kbluetooth (0.4) KDE Platform Version: 4.4.3 (KDE 4.4.3) Qt Version: 4.6.2 Operating System: Linux 2.6.32-22-generic x86_64 Distribution: Ubuntu 10.04 LTS -- Information about the crash: I've had working kbluetooth configuration a month ago on Kubuntu Lucid, after that I've installed blueman package with aulirus. After removing blueman (and rebooting the system) I've tried once more kbluetooth and it had no device name, MAC 00:00:00:00:00:00 and visibility set to invisible (I've had discoverable before). When I try to set device name and accept configuration kbluetooth crashes. Tried on both official KDE 4.4.2 in Kubuntu Lucid and 4.4.3 from Kubuntu PPA. The crash can be reproduced every time. -- Backtrace: Application: KBluetooth (kbluetooth), signal: Segmentation fault [Current thread is 1 (Thread 0x7f6b9931c760 (LWP 8260))] Thread 2 (Thread 0x7f6b8755e710 (LWP 8264)): #0 0xffffffffff60017b in ??

It looks like a hardware bug. After powering off and on my laptop kbluetooth worked without problems properly saw my bluetooth device and now it doesn't crash when changing adapter settings. I've been rebooting and powering on and off device (hardware switch) before and this didn't help, I had to shutdown system and power it on again but and problem was not only the kbluetooth - every bluetooth application had simmilar problems here. Sorry for confusion.
