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.

plasma-desktop (0.4) on KDE Platform 4.10.00 "release 546" using Qt 4.8.4

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.

The apport log for the same time period (at least 25 crashes in there)

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[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.

[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?

plasma-desktop (4.10.5) on KDE Platform 4.10.5 using Qt 4.8.5

Plasma seems to crash at random times. There is no one activity that is suspect. Sometimes, I will be active on the computer. Othertimes, it's sitting idle. Most of the time, Plasma restarts itself. Every once in a while, I have to restart it manually.

- What I was doing when the application crashed:
I was browsing the internet with Iceweasel. Plasma-desktop crashed (never happened before 4.10.5)

- Unusual behavior I noticed:
Usually, plasma-desktop restarts, but from time to time, it doesn't, I have to relaunch it manually.

[themroc (rauchweihe)]

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.
