Application: systemsettings (5.27.80) Qt Version: 6.6.0 Frameworks Version: 5.240.0 Operating System: Linux 6.2.0-26-generic x86_64 Windowing System: X11 Distribution: KDE neon Unstable Edition DrKonqi: 5.27.80 [CoredumpBackend] -- Information about the crash: I can consistently make System Settings crash if I switch too fast between KCMs. It's easier to reproduce in the Appearance section. Since I'm using a VM, switching between KCMs is slower than normal, so it will probably be harder to make it crash on a real machine. On the VM I can make SySe crash with the mouse cursor very easily, for a real machine I suggest the following: 1. Go to the Appearance category 2. In order to switch between categories very fast, spam the up/down arrow and enter keys in rapid succession. This will hopefully make it possible to reproduce the issue. This issue is NOT present on Plasma 5.27 Unfortunately I couldn't install the debug symbols because the proccess responsible for doing that in Dr. Konqi crashes. The crash can be reproduced every time. -- Backtrace (Reduced): #7 0x00007f9e97fabe1c in qt_qFindChildren_helper(QObject const*, QMetaObject const&, QList<void*>*, QFlags<Qt::FindChildOption>) () from /lib/x86_64-linux-gnu/libQt6Core.so.6 [...] #9 0x00007f9e97fa777c in QObject::event(QEvent*) () from /lib/x86_64-linux-gnu/libQt6Core.so.6 #10 0x00007f9e99189596 in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /lib/x86_64-linux-gnu/libQt6Widgets.so.6 #11 0x00007f9e97f5a128 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () from /lib/x86_64-linux-gnu/libQt6Core.so.6 #12 0x00007f9e97f5e0f8 in QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) () from /lib/x86_64-linux-gnu/libQt6Core.so.6 Reported using DrKonqi
