Bug 188966

Unfortunately the backtrace we received downstream isn't much better. But at least it's a bit better :P

It was reported as crashing when shutting down bluetooth.

Oh, and as a note this happens when shutting off bluetooth.

Hi
This should be fixed in the 0.4 version, can you test it again please?

Thanks!

We received a duplicate report of this crash from someone running 0.4-beta1b (https://launchpad.net/bugs/437732)

Hi, this bug should be fixed now, as it seems to be a duplicated of: https://bugs.kde.org/show_bug.cgi?id=212607

I'm going to set as resolved->fixed. If anybody is able to reproduce it again please, reopen it again.

Thanks for reporting!

In which one version should we expect the fix?
I'm on openSUSE's KDE 4.3.3, release 2 and kdebluetooth4-0.3-11.1.i586, but still crashes.

This have to be fixed in the 0.4RC2 version, is up to your distribution to upgrade since right now seems that you're using a very old version (0.3).

Yes, i can confirm kbluetooth-0.4_RC2-1.1.i586 fixes the crash.Great work.
Thanks for fixing :-D
