kbluetooth4 crashed with SIGSEGV in Solid::Control::BluetoothManager::findBluetoothInterface()

[Craig Magina]

Binary package hint: kdebluetooth

I had updated my machine, logged out, restarted X and then logged back in. The apport icon was in the taskbar and here we are. The kbluetooth4 app is still running, as I see the icon in the taskbar and I am able to interact with it.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Is this reproducible? Has this happened again lately?

[Pascal d'Hermilly (pascal-tipisoft)]

yes, just happened to me upon startup. Fully updated.
see bug 273753 for LOTS of debug information

[Martin Nowack (martin-nowack)]

This happened for me too with a fully updated system. After using the killswitch on a T60 to disable wireless and switch on again it kdebluetooth4 segaulted.

[Tore Anderson (toreanderson)]

Happened to me today with a fully updated Intrepid.

Same here...

[Reinhard (enterldestodes)]

I assume that my bluetooth stuff always crashes when I suspend the system while bluetooth is being actively used, in my case as a modem, using pon for the connection over bluetooth/umts mobile.

[Salze (stefan-sarzio)]

I've just had that crash, too. I'm transfering some videos from my mobile to the notebook. As far as I can tell the transfer continues as normal and I can see no real problem.

I'm using Intrepid beta. Launchpad says that debugging information have been added automatically. Is that also true when subscribing to an existing bug, or just if I had chosen to open a new one?

[Craig Magina (craig.magina)]

It crashed for me when waking up from suspension. There had been a mouse attached when it went to sleep.

[Matt Neilson (ichthyoboy)]

I had the same crash upon wake from suspend.

[Boris Rybalkin (ribalkin)]

I've just restarted X ctrl+alt+backspace and I see that message.
Ubuntu Intrepid 64.

[Jonathan Thomas (echidnaman)]

Fixed with kdebluetooth 0.3 in Jaunty. The fixed version will be making its way into Intrepid soon.
