plasma-desktop crashes repeatedly

[abmoraz]

Since upgrading Kubuntu from 12.10 to 13.04, plasma-desktop has crashed repeatedly. I used to have a few crashes here or there (every week or 2) in 12.10 (especially when using the comics widget), but since upgrading, it crashes whenever I:
   - switch application windows
   - switch desktops
   - change tabs in firefox
   - access any desktop widget
   - try to add a widget

I have removed as many of the desktop widgets that I can to eliminate them. I still have:
   - A standard panel
      -- KDE Application Launcher
      -- Show Desktop
      -- Task Manager
      -- Pager
      -- System Tray
      -- Digital Clock
   - Twitter

I have NOT been able to fill out an automated crash report, as the desktop crashes and restarts when I try an open the crash reporter. I can force a crash every time by trying to add/remove/modify any widget.

I have run plasma-desktop from terminal and this is the output I get when it crashes:

   KCrash: Attempting to start /usr/bin/plasma-desktop from kdeinit
   sock_file=/home/rwilburn/.kde/socket-rwilburn-pc/kdeinit4__0
   KCrash: Application 'plasma-desktop' crashing...
   KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
   sock_file=/home/rwilburn/.kde/socket-rwilburn-pc/kdeinit4__0

The full terminal output is uploaded as the attachment "terminalOutput.txt".
kdm.log is empty
apport.log is attached

I have never been able to get the debugging symbols for plasma-desktop to install. Everytime I try to do it via the crash handler, it says they install, then sends me back to saying I need to install them (repeat in endless loop). If someone can tell me the package name and repository, I will install them and try to run the crash handler again.

If there is anything else I can provide, please let me know.

I have had this crash in a number of cases, independently of what I was doing, sometimes surfing with firefox, sometimes typing documents in kile, etc. I always keep a number of applications open, so I cannot tell if it is application related.
It happens occasionally to me (3-5 times per day).

I just checked the Qt 4.8 sources, and it's probably a QtDeclarative bug (again).

Qt developers, however, need a reproducible test case, so if a Plasma developer knows how to create a simple QML test case, please add a comment.

See also https://bugreports.qt-project.org/browse/QTCREATORBUG-7941

[Christoph-maxiom (christoph-maxiom)]

From looking at the comments, it is the notifications applet which is using those QML list models.

Veromix, Amarok, Thunderbird, Liferea, Kopete, Networkmanagement
Hidden: Wallet, Klipper, Battery, Device Notifier

Can it be somehow caused by Firefox? Seems like all the people above were using it. What for me, I used Chromium before and this crash on current KDE version (4.10.1) didn't happen. Sorry for my english.

I was using Chromium. Firefox was also open at the same time, though.

I had crashes when Firefox was not running.

Shouldn't this be marked as regression? After all, it did not happen with the previous notification implementation.

So do we have any ideas of how to mitigate things until the QtDeclarative architecture is fixed or KDE finds a workaround to not trigger the code path? I'm having it happen both under Nouveau and nVidia's binary driver both. Oddly enough, my work computer has Intel graphics and I don't have the crashes under that and both have Fedora 18 and are at the same software versions.

- What I was doing when the application crashed:

Just in case someone was wondering, the crash can still occur with latest Qt/4.8 branch, and latest KDE (libs, workspace, etc) master.

@Christoph, unfortunatelly, the problem is that it cannot be reproduced at will. So it'll be a tough one to fix.

[Harald Sitter (apachelogger)]

Please post the crash handler backtrace regardless.

[abmoraz (abmoraz)]

I forced another crash (not difficult, I can do it on demand by starting the plasma-desktop and clicking on pretty much any widget) and attached the backtrace.

Timeline:
- Started plasma-desktop from console
- crashed
- plasma-desktop restarted on its own
- the "KDE Crash Handler" ran on its own
- I generated the back trace
- while the backtrace was running (no other applications were clicked or used while it was generating), plasma-desktop crashed again.
- plasma-desktop auto-restarted again (backtrace still generating)
- plasma-desktop crashed again (backtrace still generating)
- plasma-desktop did NOT auto-restart this time
- backtrace completed (but gave the "you need to install debugging symbols" warning)

I have tried to install the debugging symbols no less than a dozen times. They do not seem to install. If you can point me towards a packed/repository that contains them, I will try and manually install them.

-- I have tried to install the debugging symbols no less than a dozen times. They do not seem to install. If you can point me towards a packed/repository that contains them, I will try and manually install them.

[abmoraz (abmoraz)]

After reading through the duplicate issue that was imported, I decided to disable "Notifications" from my "System Tray" widget in my main panel. Since doing that, I haven't crashed. It's only been 20 minutes, but prior to that, I would crash after ~20-30 seconds.

Seems like a short-term workaround is to disable that portion of the System Tray.

[abmoraz (abmoraz)]

It's been almost 2 hours and no crashing since disabling "Notifications". If it's not the "Notifications" widget embedded in the "System Tray" widget, then it appears that it has something to do with how plasma-desktop handles that widget.

[O-brian (o-brian)]

For the time being my method of "fixing" it is to disable the notifications applet. It's not optimal but keeps kwin from crashing at least.

It has been over 24hours now without crashes (where I was crashing in seconds before). I can confidently say that it was the "Notifications" that was causing the crashes for me. Disabling it from the System Tray Widget is a viable short-term workaround.

on my opensuse 12.3 with KDE4.10.2 and graphics card = NVIDIA Quadro NVS 3100M and I'm using proprietary 304.88 nvidia drivers from the opensuse nvidia repo, crashes happens also in the other installation on the same pc with nouveau drivers.
after having read this issue I disabled notifications from the system tray, rebooted launched luckybackup and after few minutes the crash happened.

I was running only luckybackup, the crashes happens very often, one week ago I deleted the ~/.kde4 folder, the crashes stopped, but day by day the crashes becomes more frequents, now even just started kde and many times a day, kwin works ok I think becouse beclock works, alt>f2 works well becouse is the only way to interact wit the system

as the crash windows don't works well becouse it says me to click on the install packages but if I click there nothing happen, so I installed all the debug packages and created this backtrace hoping to be useful:
thanx, ciao, pier :-)

*sigh*
A bunch of KDE updates (including plasma-desktop) came through my system update this morning (via stable channel). I installed them; now the crashes have started all over again :(

Notifications are still off, but I am crashing repeatedly again.

The crash seems to be reproducible when:
- I am in settings of control panel
and
- a notification appears.

[themroc (rauchweihe)]

After upgrading to Kubuntu 13.04 with KDE 4.10.2 plasma-desktop crash randomly on all my Kubuntu PC's. Sometimes on one of the three Kubuntu PC plasma-desktop crashes before the upgrade too. But now plasma-desktop crashes more often and on one PC sometimes permanently.

It is not all times a reproducible action before the crash.
But often either I was before the crash with the Mouse in the lower right corner in the control panel, or often I had click before the crash in the lower right corner in the control panel "show hidden symbols". Or often after a pop up appears and ask for some input (e.g. password).

[themroc (rauchweihe)]

Now I found an every time reproducible crash on one of my Kubuntu 13.04 64bit PCs with KDE 10.2:

Opening (clicking) this Desktop-File on Workspace due to an crash off plasma-desktop:

That .desktop file works all right here. It opens the pdf document in Firefox, and that's it. Plasma is not even involved.

Which default browser do you use?

NO, my .desktop file open an animated gif.

My default browser is Konqueror, but http://www.dwd.de/wundk/radar/Radarfilm_WEB_DL.gif opens in Gwenview by default for me.

But now I have detect, that this .desktop file doesn't lead to an crash on my Kubuntu 13.10 PC at work.

I think, plasma-desktop crashes if a notification and something else (opening a new application or a window or something else) should happens on same time.

[Ralf Jung (0tlwui8x-post-kj985rvy)]

Sorry, of course I meant gif. I changed the default browser (could not get it to launch in Gwenview though), still not crashing here (KDE 4.10.3).

Kubuntu 13.10 is not yet released, in fact that's still 6 months ahead ;-)

[O-brian (o-brian)]

So here's what I've found so far. My work laptop has an Intel chipset and a 64-bit install of Fedora 18. I've never had the notification widget crash the desktop there. My home computer has a nVidia card and was a 32-built version of Fedora 18 and was having crashes all the time. I reinstalled with a 64-built Fedora 18 build and still had the issues. The only way I've been able to keep kwin from dying is to disable the system tray notifications widget. I've read elsewhere it's a code path issue in Qt that KDE 4.10+ triggers that wasn't triggered in the past and could require a significant rewrite of Qt to fix. Also doesn't seem to happen on either system with compositing disabled, but I like my eye candy ;)

So for me, it seems to get triggered more often with kwin running compositing on nVidia cards than Intel cards. You guys having issues might try disabling the notification widget. Yeah, notifications can pop in the middle of the screen, but at least the don't bring kwin down with them.

[Ralf Jung (0tlwui8x-post-kj985rvy)]

This bug is about a crash in plasma, not kwin. So I assumed you always meant plasma when you said kwin?

Also, I have an Intel card, and I saw this crash a few (3-5) times. It doesn't seem to be driver-dependent (and also, that wouldn't make much sense... whatever that means^^).

I upgraded from 4.10.2 to 4.10.3 and rebooted. Now plasma-desktop crashes as soon as it starts. I can't use KDE at all anymore. I should have known better than to upgrade. So much for "bug fixes only." This QML stuff is not ready for primetime. KDE should wait until it's stable before pushing it out on trusting users. Porting to fancy new stuff is not urgent or important. Stability is what matters most.

[fsando (fsando)]

Ok I've been through a few days of this madness of constant crashes. I finally seem to have fixed it by changing permissions on everything in /var/tmp to 777.

I don't know why this works but there hasn't been even the slightest hint of an issue since (going for 1 day now)

[fsando (fsando)]

Update:

The crashes continued

I have caught the last crash with strace:

$ strace -ff -tt -v -s 1024 -o odir/ofile.txt plasma-desktop

If the trace files are useful please let me know.

[Adam Porter (alphapapa)]

fsando, if you can post the traces with the versions you have installed of all the relevant packages, go ahead. Also if you can post your ~/.kde/share/config/plasma*rc files, that might at least help figure workarounds.

This may only be a workaround and not address the actual bug, but I removed ~/.kde/share/config/plasm* while logged in through a console only. This resets all of the plasma settings back to the defaults. I reconfigured everything back to the way I had it and I have not had a crash since (3-4 weeks). It's a big pain but it's better than having plasma-desktop crash almost every time I get a notification or switch windows.

Ok, some more info on this bug:

I was experiencing this bug on my work computer (Intel dual processor with Intel Graphics card) and on my home computer (AMD quad core processor with ATI radeon 4xxx series card using the legacy drivers). I upgraded my ATI card to a radeon 6450 card to get off of the legacy drivers and still experienced the bug.

THEN

I bought a real big honkin' nVidia card (660t) to allow SLI and the bug just stopped. Didin't matter if I used opensource "nv" drivers or the proprietary drivers from nVidia. I can use widgets, notification, etc... with no issue. Has been that wy for almost 2 weeks now. Ever since I replaced the video card.

Seems like the issue maybe with widgets/workspace appearance and graphics accellerators. From the looks of all the other people submitting the bug, I saw a lot of ATI/AMD and Intel cards. I didn't notice if anyone was using nVidia.

[ArthurGordon (nsl)]

@abmoraz (abmoraz) :
I'm actually using a nvidia graphics card.

01:00.0 VGA compatible controller: NVIDIA Corporation GT216M [NVS 5100M] (rev a2)

[ArthurGordon (nsl)]

Now i installed Kubuntu 12.04.2 LTS and made the upgrade to Kubutu 13.04.
After the first reboot the plasma-desktop ran without any crashes but began than to crash again.
Therefore i deleted the plasma config files "~/.kde/share/config/plasm*" as described by Adam Maćkowiak (admc) and since then it runs stable (so far).

[Adam Maćkowiak (admc)]

Is this fix included in 4.11?

[Christoph-maxiom (christoph-maxiom)]

Unfortunately, there is no fix. It is not even clear if the bug is in QtDeclarative, or in the notification applet. The only workaround for now (besides removing the notifications applet) would be to use the applet from KDE 4.9 version, which does not use QtDeclarative.

[Adam Maćkowiak (admc)]

Maybe dev should rewrite notification applet to not use QtDeclarative?

For me the last crash from Plasma-Desktop is long time passing. So, for me is the Bug fixed.

[Nico-kruber (nico-kruber)]

for me this still happens occasionally (KDE 4.11.2)

very rarely, plasma-desktop even fails to restart itself automatically (which normally happens when DrKonqi is started)

Hi, Albert found a possible cause and a way to work around this issue, see https://git.reviewboard.kde.org/r/113471/

Since this is a pure QML patch, no compilation is required, so please, if possible, test it. As far as I understand, frequent simultaneously appearing/disappearing notifications could have caused the crash, so make sure you keep getting notified :)

Fix crash when removing a notification while we are adding one

Reading https://bugs.kde.org/show_bug.cgi?id=311871#c41 you can see that it happens that we are doing a
78 0x00007f4eff8c5ffb in QDeclarativeListModel::insert (this=0x1ebbdb0, index=0, valuemap=...) at util/qdeclarativelistmodel.cpp:436
and then we end up reentring and doing
16 0x00007f4eff8c737f in QDeclarativeListModel::remove (this=0x1ebbdb0, index=6) at util/qdeclarativelistmodel.cpp:402

Some of the stuff that depends on the QDeclarativeListModel doesn't seem to like getting a "remove" while a "insert" is happening and to be honest m in no mood to fix that, so basically I'm protecting against that happening in our QML code. From what i read you have to be extremely unlucky since the timer only triggers each 10 minutes and it has to trigger at the same time a notification is being added, but oh well, the backtrace points to it and two different people in two different systems say it has stopped the crashes so I don't think it hurts to have this in.

plasma-desktop (4.10.5 "release 1") on KDE Platform 4.10.5 "release 1" using Qt 4.8.4

- What I was doing when the application crashed:
- I am opening many application, and also wine application (chat messenger LINE)
- I am writing a document.

- Custom settings of the application:
I am using a dark theme.

Note : I often feel that the crash is repeating itself at a certain interval of time regardless of the number and what application I used.

Finally! After 10 months devs fixed this annoying bug by adding four lines of code! Good to see it fixed because I already started considering migration to another, more stable DE.

Bad news: bug 327770 is against KDE 4.11.3. But to be sure it was not with old plasma still running after update, let's wait if there are more bug reports.
