Description Frode Jemtland 2011-01-04 08:58:39 UTC
Application: kded4 ($Id: kded.cpp 1031637 2009-10-05 16:58:19Z lunakl $)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

-- Information about the crash:
This time the chrash appered when I suspended from hibernation. I don't think it is related to the hibernation process. I have seen this chrash when I change from wireless to wired network, or the other way. It has also happend when I turn on the wireless-kill-switch. To me it seems to have something to do with the network change.

After the KDE Init has crashed the icons in the system tray are acting strange. Some of the icons apperes duplicate times, and some of the icons are on top of eachothers. Even the clock seems to be pushed "out of the screen". (I have the clock in my low right corner, and the system tray is left of it.) 

I'm running a stock KDE 4 on a Debian squeeze system. 

The problem has been there for a couple of months.

What BlueDevil version do you have?

New crash information added by DrKonqi

Resuming from hibernation with a different network environment caused this crash.  Debian Squeeze:

bluedevil:
  Installed: 1.0~rc3-2
  Candidate: 1.0~rc3-2
  Version table:
 *** 1.0~rc3-2 0
        990 http://ftp.us.debian.org/debian/ squeeze/main i386 Packages
        100 /var/lib/dpkg/status
Comment 3 Alex Fiestas 2011-09-18 02:16:18 UTC
Can you test with a modern BlueDevil, 1.1.1 or 1.2.1?

At the very least latest 1.0.4

Thanks.

Replaced AgentListener (QThread) by delayed DBus messages

This thread has been causing many crashes for some people, and
as far as I remember all the backtraces show weird things not really
within BlueDevilcode, and of course none of the BlueDevil developers has
been able to reproduce the bug. So the best/easy/simpler way of fixing
this is by removing the Thread which shouldn't be there in the first
place.
