Application: plasmashell (5.27.80) Qt Version: 5.15.8 Frameworks Version: 5.104.0 Operating System: Linux 5.19.0-35-generic x86_64 Windowing System: X11 Distribution: KDE neon Unstable Edition DrKonqi: 5.27.80 [CoredumpBackend] -- Information about the crash: Recently plasmashell has been unstable on my system. In the case I'm reporting and most other cases I can remember plasmashell is crashing when I click on an application icon in the taskbar to try to switch applications. It does not occur every time, but seems to be occurring once every hour or two of usage currently. The crash can be reproduced sometimes. -- Backtrace (Reduced): #3 0x00007f3675fcdf30 in QSGAreaAllocator::deallocateInNode(QPoint const&, QSGAreaAllocatorNode*) () at /lib/x86_64-linux-gnu/libQt5Quick.so.5 #4 0x00007f3675fcdfaa in QSGAreaAllocator::deallocate(QRect const&) () at /lib/x86_64-linux-gnu/libQt5Quick.so.5 [...] #13 0x00007f3673a94b43 in start_thread (arg=<optimized out>) at ./nptl/pthread_create.c:442 #14 0x00007f3673b26a00 in clone3 () at ../sysdeps/unix/sysv/linux/x86_64/clone3.S:81 [...] #8 0x00007f3675ab360a in QQmlType::create(QObject**, void**, unsigned long) const () at /lib/x86_64-linux-gnu/libQt5Qml.so.5 The reporter indicates this bug may be a duplicate of or related to bug 462400, bug 466395.

Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: > #6 0x00007f3667f7892e in () at /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/core/libcorebindingsplugin.so > #7 0x00007f3667f522af in () at /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/core/libcorebindingsplugin.so Could you please install debug symbols for Plasma, reproduce the crash, and attach a new symbolicated backtrace?
