Application: systemsettings (6.1.0) Qt Version: 6.7.1 Frameworks Version: 6.3.0 Operating System: Linux 6.9.4-200.fc40.x86_64 x86_64 Windowing System: Wayland Distribution: "Fedora release 40 (Forty)" DrKonqi: 6.1.0 [CoredumpBackend] -- Information about the crash: Systemsettings crashes after opening sound -> switching to a different module -> sound. This does not seem to occur on other modules. Not sure if related, but after the update to 6.1.0 the device names in the sound applet are different. However they have not changed in the settings module. For example: HDMI / DisplayPort (GP104 High Definition ...) -> HDMI 0 The crash can be reproduced every time. -- Backtrace (Reduced): #5 operator() (__closure=0x55c8d4806090) at /usr/src/debug/qt6-qtdeclarative-6.7.1-2.fc40.x86_64/src/qmlmodels/qqmldelegatemodel.cpp:1915 #8 QtPrivate::QCallableObject<QQmlDelegateModel::_q_modelAboutToBeReset()::<lambda()>, QtPrivate::List<>, void>::impl(int, QtPrivate::QSlotObjectBase *, QObject *, void **, bool *) (which=<optimized out>, this_=0x55c8d4806080, r=<optimized out>, a=<optimized out>, ret=<optimized out>) at /usr/include/qt6/QtCore/qobjectdefs_impl.h:555 #9 0x00007fcfd37fa752 in QtPrivate::QSlotObjectBase::call (this=0x55c8d4806080, r=<optimized out>, a=0x7ffd929e65b0) at /usr/src/debug/qt6-qtbase-6.7.1-2.fc40.x86_64/src/corelib/kernel/qobjectdefs_impl.h:469 #10 doActivate<false> (sender=0x55c8d50a7c30, signal_index=21, argv=0x7ffd929e65b0) at /usr/src/debug/qt6-qtbase-6.7.1-2.fc40.x86_64/src/corelib/kernel/qobject.cpp:4086 [...] #12 0x00007fcfd3a00ba0 in QAbstractItemModel::modelReset (this=<optimized out>, _t1=...) at /usr/src/debug/qt6-qtbase-6.7.1-2.fc40.x86_64/redhat-linux-build/src/corelib/Core_autogen/include/moc_qabstractitemmodel.cpp:1112 Reported using DrKonqi
