as a workaround use the Breeze decoration. "quelle surprise" ... PS, @Pedro run "kcmshell5 kwindecoration" and select the breeze decoration to avoid this crash. Things like the tabbox, the desktop switching indicators or the buttons in desktopgrid/presentwindows might still cause such crashed (thus less likely) *** Bug 363045 has been marked as a duplicate of this bug. *** *** Bug 363196 has been marked as a duplicate of this bug. *** Reported upstream bug report: https://bugreports.qt.io/browse/QTBUG-53452 *** Bug 363221 has been marked as a duplicate of this bug. *** *** Bug 364083 has been marked as a duplicate of this bug. *** *** Bug 364121 has been marked as a duplicate of this bug. *** *** Bug 364453 has been marked as a duplicate of this bug. *** *** Bug 364632 has been marked as a duplicate of this bug. *** *** Bug 364690 has been marked as a duplicate of this bug. *** *** Bug 364842 has been marked as a duplicate of this bug. *** *** Bug 364881 has been marked as a duplicate of this bug. *** *** Bug 365170 has been marked as a duplicate of this bug. *** *** Bug 365593 has been marked as a duplicate of this bug. *** *** Bug 365644 has been marked as a duplicate of this bug. *** *** Bug 365842 has been marked as a duplicate of this bug. *** *** Bug 365896 has been marked as a duplicate of this bug. *** *** Bug 365988 has been marked as a duplicate of this bug. *** *** Bug 366012 has been marked as a duplicate of this bug. *** *** Bug 366096 has been marked as a duplicate of this bug. *** *** Bug 366097 has been marked as a duplicate of this bug. *** *** Bug 366126 has been marked as a duplicate of this bug. *** *** Bug 366240 has been marked as a duplicate of this bug. *** *** Bug 366198 has been marked as a duplicate of this bug. *** *** Bug 366331 has been marked as a duplicate of this bug. *** *** Bug 366393 has been marked as a duplicate of this bug. *** *** Bug 366443 has been marked as a duplicate of this bug. *** *** Bug 366761 has been marked as a duplicate of this bug. *** *** Bug 367733 has been marked as a duplicate of this bug. *** *** Bug 367862 has been marked as a duplicate of this bug. *** *** Bug 367951 has been marked as a duplicate of this bug. *** *** Bug 368993 has been marked as a duplicate of this bug. *** *** Bug 369013 has been marked as a duplicate of this bug. *** *** Bug 369534 has been marked as a duplicate of this bug. *** *** Bug 369591 has been marked as a duplicate of this bug. *** *** Bug 369907 has been marked as a duplicate of this bug. *** *** Bug 370174 has been marked as a duplicate of this bug. *** *** Bug 370432 has been marked as a duplicate of this bug. *** *** Bug 370512 has been marked as a duplicate of this bug. *** *** Bug 370614 has been marked as a duplicate of this bug. *** *** Bug 370624 has been marked as a duplicate of this bug. *** *** Bug 370724 has been marked as a duplicate of this bug. *** *** Bug 370999 has been marked as a duplicate of this bug. *** *** Bug 371802 has been marked as a duplicate of this bug. *** *** Bug 371824 has been marked as a duplicate of this bug. *** *** Bug 371839 has been marked as a duplicate of this bug. *** If developers are unable to reproduce / debug the crash, perhaps I can help, when you tell me where to insert debug output, or even better send me a modified binary (.so) with debug output.

Thanks for the offer. What we need most is a reliable way to reproduce the problem. Currently all we know is that opening some windows crashes it. But as I have never hit it myself, there must be something extremely important to trigger the crash. At the moment we are rather clueless at what could trigger the crash. We just don't see anything in the backtrace due to it being Qml. Once we would be able to reproduce we could investigate properly and figure out the condition. So what's most important is to figure out how to reproduce it. For me, the crash occurs every time I log into the system (and some programs start automatically, they were saved in the previous session). I just figured out how I can reproduce the fault every time. If I follow this sequence, kwin will always crash on a segmentation fault - 1. login to kde 2. After logging in, open dolphin, and leave the window open 3. Open libreoffice write, and then close it 4. Open kwrite, and then close it. 5. Open konsole. This is when kwin crashes. Every time. I haven't tested it on opening other applications, but so far this sequence will consistently reproduce the crash. Here is my backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Is there anything I can supply (other than a small test case)?
Tried to find out what in method QV4::Value::as should happen.
I _think_ the loop is entered with more or less the _val member
casted to const QV4::VTable *.
At least when I try this manually I end up with the same invalid pointer.
So it looks like the parents parent pointer got truncated somehow:

#33 0x0000000000400809 in _start () Backtrace from comment #63 still shows it crashes because of Aurorae theme. You are right. I thought I changed the theme but somehow it wasn't completely changed. After solving that, Kwin didn't crash anymore. Sorry for the confusion. I hope you'll find the cause. And to be honest I do like the new Plasma 5 desktop. It's only a pitty that it's just not "snappy". After the latest updates in Debian Testing I am not able to reproduce the crash anymore by switching from Breeze to Plastik decorations. The updates contained mostly Qt from 5.6.1 to 5.7.1~20161021. And some packages libkf5* and kwin* got just rebuilt at the same version. *** Bug 372817 has been marked as a duplicate of this bug. *** *** Bug 372962 has been marked as a duplicate of this bug. *** *** Bug 373043 has been marked as a duplicate of this bug. *** *** Bug 373170 has been marked as a duplicate of this bug. *** *** Bug 373212 has been marked as a duplicate of this bug. *** *** Bug 373413 has been marked as a duplicate of this bug. *** *** Bug 373472 has been marked as a duplicate of this bug. *** *** Bug 373604 has been marked as a duplicate of this bug. *** *** Bug 373785 has been marked as a duplicate of this bug. *** *** Bug 373800 has been marked as a duplicate of this bug. *** *** Bug 373805 has been marked as a duplicate of this bug. *** (In reply to Bernhard Übelacker from comment #66) > After the latest updates in Debian Testing I am not able to > reproduce the crash anymore by switching from Breeze to Plastik decorations. > > The updates contained mostly Qt from 5.6.1 to 5.7.1~20161021. > And some packages libkf5* and kwin* got just rebuilt at the same version. Leap 42.2: I switched to the QT5.7 / Frameworks5 repository and I couldn't see the problem any more, too. But therefore, I got a lot of other problems / crashes (e.g. with systemsettings5 and the desktop itself being suddenly completely black). Therefore I decided to switch back to original packages again and to use Breeze which works fine. *** Bug 374002 has been marked as a duplicate of this bug. *** Created attachment 102927 [details]
New crash information added by DrKonqi
kwin_x11 (5.8.3) using Qt 5.6.1

From Chromium trying to install package from opensuse page and when i press '1-click install' and new window opens for instalation software , crash message appears but all continue to work after.

May I have a question? A recent migration to Plasma 5 (on OpenSUSE Leap 42.2) has forced me to take a greater interest in the concept of activities (much of the beauty and utility of virtual desktops being lost in the new version of KDE :-(). I'm beginning to see its enormous potential, which is, however -- sadly! -- underexploited due to a number of minor but annoying design faults. Is there a place where I could share my insights and, hopefully, contribute to the conceptual development of Plasma? And, of course, my everlasting thanks to you and the KDE community for your efforts and your excellent product(s)!
