lacks backtrace informations - see here http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Backtraces The crash is in libplasma, but if "Restarting Kde session doesn't solve." and "I must restart the system." that's a kernel issue (possibly on the nvidia driver) - otherwise i'd have bet on some qDeleteAll thing. Does it happen when you just alter the resolution as well? (xrandr -q / xrandr -s <w>x<h>)
Hi Thomas.Thanks for the link ; I'll study I Thought kernel and/or drivers issues but downgrading Kernel (decrease up to 3.1.2) and/or nvidia-drivers and re-compiling KDE from svn , nothing has changed. Running KDE 4.8 in my other gentoo installation (Kernel 3.3-rc3 + ati-drivers) I have encountered the same problems.(KDE 4.8 from Gentoo portage tree) You Asked : xrandr -q --> http://pastebin.com/D5XLXcNv setting res. to 1280x1024 : no panels , desktop effects was disable , no background and bug report appears Checking : ~/.xsession-errors --> http://pastebin.com/h6qDwwBr lspci --> http://pastebin.com/nfNtRru1 Xorg.0.log --> http://pastebin.com/078ukMwk emerge info --> http://pastebin.com/0rMG01G7 glxinfo --> http://pastebin.com/BYVwrpQr Can I help you with more information ? (Now I'm gonna compile KDE from kde-overlay (SVN) and all Its dependences...) Thanks.
For testing this issue I've created a new user called "Test" This is the first xsession-errors log ---> http://pastebin.com/nCBqeVHA :( any help ?
We'd really need the backtrace of an unstripped libplasma - xsession errors contain debug statements but don't help on the crash and Xorg.0.log would only help if the X server crashed (what it apparently did not) http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Backtraces The issue is however clearly related to xrandr, we've recent reports against bug #293648 and bug #293209 - just that the provided backtrace isn't anywhere near those (in fact, it doesn't even look like it's a kwin backtrace despite the header says so) but is directly in libplasma
Hi Dr. Konqi report this after auto-login (no external drive plugged) and desktop has not panels,backgr. etc...

correction: this has NOTHING to do with xrandr, since > no external drive plugged you're not plugging external HD's but external HDD's ;-) Now, a lot of things link libplasma, but once more: THOSE BACKTRACES ARE USELESS All they hint is that plasma_applet_systemtray.so accesses SOMETHING in libplasma.so.3 which accesses SOMETHING in libQtDeclarative.so.4 that accesses SOMETHING in libQtScript.so.4 what SOMEHOW causes a segfault (while from kwin crash libplasma.so.3 accessed SOMETHING in QtCore SOMEHOW causing a crash.) This could just mean that you got the ABI breaking libpng update and didn't recompile KDE/libplasma or whatnot. If you want to figure what's the issue here (and i tend to start to believe that it's an ABI thing) you MUST create unstripped binaries as described here: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Backtraces to get rid of the question marks in the backtrace and the SOMETHING in their meaning. If you scroll down a tiny bit in that document, you'll also be directed here: http://www.gentoo.org/proj/en/qa/backtraces.xml what is gentoos own and specific description on this.

Hi Me and some users have this problem with Sabayon-Linux KDE also (Live-Dvd and after installation) In my Gentoo still goes on ... Running Sabayon Linux : I ran gdb plasma-desktop and I plugged , mounted/unmounted and unplugged USB-pen drive this is gdb output http://pastebin.com/fPTnABP0 no more.
(In reply to comment #9) > this is gdb output > > http://pastebin.com/fPTnABP0 > > no more. There's a lot of warnings about unversioned plugins, pot. resulting in instability (probably a distro issue, bundling dated plugin libraries) What is NOT in this paste is a backtrace. You cannot "gdb plama-dektop", because it forks. Either press the developer info button in the Dr Konqi dialog or run "gdb --args plasma-desktop --nofork", then "run" and after the crash "bt" The crash may however be caused by some ABI incompatible plasmoid, likely related to devices (such as the device notifier) or notifications in general.

I've done, but running "bt" after the crash show "No stack." output Step 1 : Starting program: /usr/bin/plasma-desktop --nofork warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available. QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave. plasma-desktop(12223): KUniqueApplication: Can't setup D-Bus service. Probably already running. In teh meantime I've menaged some Usb-stick (pluged,mounted etc...) Plasma Crashed Step 2 : Run "bt" in gdb after the crash No stack (gdb) DrKonqi output after the carash : --> http://pastebin.com/NdKc0i1F So I try again "run" in gdb (in the meantime Desktop hasn't backgorund , no panels...) gdb output ---> http://pastebin.com/hU5wCmCb any suggestions ?
The gdb log suggests that plasma-desktop is already running at the time you attempt to launch it. This is however pointless, since the Dr.Konqi trace shows no debug symbols either -> you need a unstripped build, best for debug, not for release. The crash however occurs from some "Plasma::PopupApplet" and in closing some svg out of /usr/lib64/kde4/plasma_appletscript_declarative.so Since i've rare knowledge about plasma itself, that's as much as i can tell.

Ok Thomas. I've this issue with all my kde installations. Here a full output of gdb : Sabayon Linux KDE-64 I only plug an USB stick and running gparted When gparted scan sdb (the usb stick) , crash starting (looping) because gpared talk with remov. device notification applet (via d-bus) . When notification applet recognize usb-stick plasma crash ; gparted scanning againg devices again and talk with d-bus Could be d-bus (or qt-dbus) the issue ? In this output you can see "Program received signal SIGSEGV, Segmentation fault" 'cause I've killed gparted to stop looping crash I hope that this can help you.
Ops : I missed pastie :D http://pastebin.com/UqyuE1QC
(In reply to comment #13) > I only plug an USB stick and running gparted errmmm ... the gparted information is new. So it does NOT crash immediately but after running gparted. Is that correct? > When gparted scan sdb (the usb stick) Next question: why are you actually doing so. Just randomly (ie. because you want) or is this somehow auto-triggered? > crash starting (looping) because gpared > talk with remov. device notification applet (via d-bus) . HOPEFULLY NOT! gparted requires root permissions, it should not start to talk with user session busses. What it however does is locking devices (via hal/udisks) what's likely somehow interpreted by the plasma dataengine. > When notification applet recognize usb-stick plasma crash Ok, what we don't know is "why" and that is because also the last backtrace does not include debug symbols. > Could be d-bus (or qt-dbus) the issue ? No. I'll pass this over to the plasmoid developers for testing.
> > When notification applet recognize usb-stick plasma crash > Ok, what we don't know is "why" and that is because also the last backtrace > does not include debug symbols. How can reproduce this ? I think running "gdb" well ... 1 - Pluggin removable-drive --> no crash 2 - Mounted device (via dolphin or Device notification) ---> no crash 3 - Closing Dolphin or umounted extern-drive ---> no crash 4 - Unpluggin external-drive --> plasma crash but with gparted it was strange ... plasma crashed with plugged drive ... :D In my desktop-pc when plasma crashed , backgorund and panels are gone while in my laptop they "restarted" I also running razor-qt Window manager and try to manage external drive/sticks razor-qt native session notifier works fine ; if i choose razor-qt (Kwin) session . and manage external-drive ... BAM ! crash .... :(
(In reply to comment #16) > How can reproduce this ? I think running "gdb" well ... If kwin would crash somewhere in libplasma here just because i happened to have unplugged a usb stick, i would have filed a grumpy bug report alongside a patch myself ;-) > 4 - Unpluggin external-drive --> plasma crash Being the ultimate source then. gparted just does sth. similar implicitly. > razor-qt native session notifier works fine ; if i choose razor-qt (Kwin) > session . and manage external-drive ... BAM ! crash .... :( Just like in the OP, and it's because a) kwin links libplasma b) SOMETHING in libplasma apparently directly reacts to the udisks signal and then crashes, taking kwin with it - so the source will likely be directly in libplasma itself, but repeating myself ONCE MORE: PLASMA DEVELOPERS WILL NEED A BACKTRACE WITH DEBUG SYMBOLS And ONCE MORE, read here how to do that: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Backtraces And since Sabayon seems to be just some gentoo derivate, ONCE MORE you'd there also find a link here: http://www.gentoo.org/proj/en/qa/backtraces.xml And for this very reason, please don't change the status again unless a usable backtrace was provided. PS: since you stated in comment #9 that "Me and some users have this problem with Sabayon-Linux KDE also (Live-Dvd and after installation)" you should connect the resp. downstream bug report / discussion so maybe someone else of the affected ppl. can provide a bugreport.
Ok plasma-workspace (and more kde build) was compiled without "debug use flag enable" I recompiled plasma-workspace withi "debug" use flag enable and now I think to have what you want :) Now plasma crashed when umount usd-stick [...] so gdb show : gdb --args plasma-desktop --nofork GNU gdb (Gentoo 7.4 p1) 7.4 Copyright (C) 2012 Free Software Foundation, Inc.

Just "pkill plasma-desktop; sleep 1; plasma-desktop", wait cause the crash, wait for Dr.Konqi, click developer information and post the output, BUT: > PS : I've comnpiled kdeplasma-workspace only with "debug" enabled.

Aaaargh !! I'll just make kdelibs as soon as possible Sir :) I don't understand 'cause "bt" doesn't show anything (only once returned an output) I'm trying to release much information as possible but often the conditions are different Please be patient :)
(In reply to comment #20) > I don't understand 'cause "bt" doesn't show anything (only once returned an > output) You only get backtraces from processes still in memory what is no longer the case when the application just exits. Plasma starts figures (or thinks?) there's already and instance and therefore quits. > I'm trying to release much information as possible but often the conditions are > different Just run kwin with the recompiled lib, add/remove an usb drive and activate the "developer information" in the Dr.Konqi dialog.
Hi kdeplasma-workspace and kdelibs compiled with "debug" flag enabled. 1 - Login to Kde-session 2 - Running gdb --args plasma-desktop --nofork --> plasma-desktop_1_gdb.log http://pastebin.com/Yt8sNuYE --> /usr/lib64/debug/usr/bin/plasma-desktop.debug http://pastebin.com/atfemnEk --> DrKonqi Developer Information http://pastebin.com/rseKhMyJ I tried again in the same session : 3 - Plug and Unplug USB-Pendrive , plasma crash but it is reloaded with his panels and background (....). I reload Drkonki Developer Information ---> http://pastebin.com/HvHfFimp So, I'm gonna login to the new session and first kill plasma-desktop pid and run gdb & company for the new test :D The strange thing is that this time plasma was reloaded with all its components after the crash :D There is something new all this does become paranoid :D

the first backtrace by abadonna crashes in a deconstructor, while the second one is in malloc -> memory corruption. Something is severely screwed up around the corebindings plugin & QDeclarativeItem If this doesn't occur anywhere else but on "sabayon" systems, it's could be a downstream issue...
Created attachment 69458 [details] Several crash dumps Hi Thomas, I'm am currently investigating the issue. But in the meantime, please find a bunch of stacktraces attached, they all show different traces eachothers and this makes me think it's some pointer being dereferenced after destruction. We have this since KDE 4.8.0 and it looks like Arch got hit by this as well: https://bbs.archlinux.org/viewtopic.php?pid=1022267#p1022267 Disabling the new QML-based Device notifier workarounds the problem. Cheers
Created attachment 69462 [details] CookBug info
Hi I've lost my previous post :/ Now i've the same problem with plasma-netbook I think DrKonqi has an reliable BT --> http://pastebin.com/uhq8NtDC Sabayon x86_64 KDE 4.8.0
Here is our make.conf (includes C*FLAGS and LDFLAGS) http://git.sabayon.org/build.git/tree/conf/intel/portage/make.conf.amd64
Just a disclaimer: I do not develop or maintain the device notifier. I don't even use it, but just carried this bug over from the kwin component and helped out to get a usable backtrace. I'll out of curiosity try whether that thing crashes the desktop here, but i won't fix it for i personally have NO knowledge about the particular code at all.
Thanks for all your patience on providing BTs; however we do need to have also qt compiled with the debug useflag to properly understand what is going on. From a superficial analysis it does seem some issue with libplasma/qml, though, rather than some specific issue in the device notifier. Let me CC notmart, since he is the most knowledgeable person about this. Thanks
So I made a nice discovery. We were compiling the Qt4 stack with GCC 4.6 and Graphite + -ftree-vectorize, as sown in the CFLAGS variable in make.conf.amd64 file linked above. Disabling Graphite and -ftree-vectorize fixed all these segfaults. Perhaps it's about instruction reordering (due to strict-aliasing) or missing volatiles? Compiling with plain "-O2 -march=x86-64" fixed the issue downstream then.

I can confirm this. Last qt-* upgrades fix this. (Sabayon) I've recompiled Qt-* packages without Graphite and ftree-vectorize in my Gentoo and this fix all the problems Thanks a lot Fabio. (and Thomas for the patience :) )

Excellent find, please report this issue upstream! > > Compiling with plain "-O2 -march=x86-64" fixed the issue downstream then.
