Version: (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages I am using a Thinkpad T61 laptop with buildin bluetooth hardware If I switch the hardware bluetooth on, a bluetooth symbol in the statusbar shows up. If I switch the bluetooth hardware off after that, KBluetooth4 crashes. There is a hardware-switch in my T61 laptop with which you can switch the w-lan and bluetooth hardware on and off, and then there is a key combination (Fn+F5) which toggles between w-lan + bluetooth, w-lan only, bluetooth only. It does not matter which method I use, KBluetooth4 crashes. The Bugreport tool says a backtrace is not possible.
If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks
ok, this was my first time with gdb. I think, I could have get more out of it, but installing the packets mentioned in the previous posted link and using gdb on kbluetooth4 only gave me the following at time of the crash: Program received signal SIGSEGV, Segmentation fault.

I can confirm the bug on Lenovo 3000 Y310 laptop. I started this notebook with Bluetooth and Wi-Fi on. Then after few minutes, without connecting anything, I turned off Bluetooth using Fn+F6. KBluetooth crashed immeidiately. Using close switch also produced the same effect. KDE crash dialog said: "A Fatal Error Occurred The application KBluetooth4 - The KDE4 Bluetooth Framework (kbluetooth4) crashed and caused the signal 11 (SIGSEGV). Please help us improve the software you use by filing a report at http://bugs.kde.org. Useful details include how to reproduce the error, documents that were loaded, etc." when told it to showed detail it said: "Unable to create a valid backtrace. This backtrace appears to be of no use. This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash." My OS is Kubuntu 8.10 using KDE 4.2.2 on Intel Core 2 @1.8 GHz and 3GB memory. Wi-Fi was always on during the incident.
Bluetooth support has been replaced by "BlueDevil" and the old code is no longer maintained. If you still have an issue with Bluetooth support in a recent KDE version, such as KDE 4.9.5 or 4.10, please report a new bug. Also, if this is a feature request that has not yet been implemented in BlueDevil, please add a comment.
