[Comment from a bug triager] From bug 272807 (KDE SC 4.6.0): - What I was doing when the application crashed: Like the possibly related bug stated below, I also had a (paused) virtualbox guest running and also in my case the suspend works usually fine. The clock "in the tray" was showing old time for a while. Perhaps this is normal but I have never noticed before. *** Bug 272807 has been marked as a duplicate of this bug. *** Can anyone test a patch for this bug? Git commit fd6fa391f6ed7dbed7072e8c90247dda09d281d1 by Alex Fiestas. Committed on 07/10/2011 at 18:50. Pushed by afiestas into branch 'master'. 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.

Application: kded4 ($Id: kded.cpp 1204125 2010-12-06 11:17:10Z dfaure $) KDE Platform Version: 4.5.95 (4.6 RC2) Qt Version: 4.7.1 Operating System: Linux 2.6.34.7-0.7-desktop x86_64 Distribution: "openSUSE 11.3 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: Just resumed from standby (suspend to ram). this is the first time that that crash happened. Usually resume from str works just fine. One more note, this time I had a virtual box guest machine running, though not sure if that has anything to do with kde deamon. -- Backtrace: Application: KDE Daemon (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0x7f452b76c760 (LWP 2580))] Thread 3 (Thread 0x7f450f5f9710 (LWP 2588)): #0 0x00007f4528e436b3 in poll () from /lib64/libc.so.6 #1 0x00007f4525cb5fd4 in ??
