systemsettings (1.0) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

I'm switched color themes, styles, plasma styles, etc. On close got a crash, and it is repeated several times.

> bug in the raster paint engine 

You changed the bug to "resolved upstream" (I presume you mean in Qt) in November 2011; however, I still experience this crash in the QRasterWindowsSurface destructor:

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

I thus have to ask: Which Qt version is supposed to include the fix? Is there a Qt ticket for this issue?
 
> (and why is this bug filed against plasma if it is system settings that is
> crashing? :)

Well, in my case the notifications says plasma-desktop crashed. And plasma crashes on shutdown even though I don't have system-settings open.

The bug happens everywhere (just google "~QRasterWindowSurface segfault")

The issue seems that QWidgets are deleted _after_ the application and Qt says it's not a Qt bug:
https://bugreports.qt-project.org/browse/QTBUG-16974

So anything that somehow uses KSelectionWatcher or some autodeleted global widget (in plasma's case kidletime seems to be the cause) is prone to this bug.

The issue is directly caused by the raster graphicssystem but i also smell the glib dispatcher here.

Since plasma might drop to lousy performance when using the native graphicssystem and the opengl graphicssystem is still too buggy, you could -as an instant workaround- try to simply get rid of the glib dispatcher first, see whether the issue remains and report your findings:

in ~/.kde/env have some script
export QT_NO_GLIB=1

However given the upstream statements, questionable or not, kdelibs and all affected applications will need to fix this.

This particular crash is either in systemsettings or *might* have been caused by the oxygen(-transparent) style, which eventually has been fixed in this regard as well as by the bespin style (but i've never seen such crash myself) - unfortunately we only know that the globalstaticdeleter deleted "a" QWidget :-(

Since the bug was last reported for 4.7.2 i'll set it "waiting for info" unless we get an update regarding KDE 4.8 for *this* particular crash.

Your bug is however unlikely upstream either, but please look for the correct duplicate (there's for sure...) and hook on there.

-----

FTR:
"Resolved upstream" is just a funny way to say "Somebody else's problem" - it's doesn't actually mean the bug is reported or even fixed.

Can anybody confirm *this* particular bug (segfault in systemsettings or maybe a directly invoked kcm) for KDE >= 4.8?

plasma-desktop (0.4) on KDE Platform 4.8.2 (4.8.2) using Qt 4.8.1

- What I was doing when the application crashed:

The crash still happens as soon as I log out, even though I placed a script into ~/.kde/env that sets the environment variable as suggested two comments above.

Please note this is on KDE 4.8.2.

Bug 324407 reveals an interesting detail. The global widget to be deleted after QApplication destruction could actually be a Qt widget.

http://qt.gitorious.org/qt/bibrs-qt/commit/f900144fdb7e5b811011315a98b7ea7ed9a80f32 reveals a global "globalStyleInfoWidget", part of QGraphicsLayout. Not sure if it is still used in Qt 4.8.

Forget my last remark, bug 324407 was using latest Qt.

Good news, the globalStyleInfoWidget will be gone with Qt 5.3.0. I doubt Qt 4.x will see any change.

Remaining is the global QWidget from libkidletime.

This happens to me every day with almost every program I use. Just shutting down my computer causes KDE Crash handler dialogs to pop up everywhere. Nothing can close without a segmentation fault.

*** Bug 334146 has been marked as a duplicate of this bug. ***

I can confirm this bug. It doesn't depend on amarok especially, also gwenview aso. are crashing.
Using the latest version of KDE 4.13 on openSUSE 13.1 (64 bit).

I posted a temporary solution to this on my blog. It makes the crash dialogs go away at least http://poisonpacket.wordpress.com/2014/05/06/the-kde-bug-that-makes-crash-reports-appear-whenever-you-close-an-app-that-has-not-been-fixed-in-the-4-years-since-it-was-reported/

Define "transparent windows" - if it's linked to a particular GUI style (oxygen-transparent, qtcurve, bespin) this (massive crashing) can probably be fixed/avoided.

If you've so far only tested one or two of those, try the other one(s) and report tested version and findings (crashes as well/not - notice that applications that were running while changing the style will probably still crash, only new processes are relevant)

- What I was doing when the application crashed:

This happens every time when I close the gwenview application. I think kmix also crash when I login out. The main cause is the use of oxygen-transparent theme for application. When I switched to oxygen, the things work as expected. 

The crash can be reproduced every time.
