Application: kontact (5.22.3 (22.12.3)) (Compiled from sources) Qt Version: 5.15.8 Frameworks Version: 5.105.0 Operating System: Linux 6.2.3 x86_64 Windowing System: X11 Distribution: "Gentoo GNU/Linux" DrKonqi: 5.27.4 [KCrashBackend] -- Information about the crash: I've noticed that sometimes Kontact crashes when I open configuration dialog. The only thing I had to to is, maybe, move a cursor through some QtWidgets, But maybe it is time-related. The crash can be reproduced sometimes. -- Backtrace: Application: Kontact (kontact), signal: Segmentation fault [KCrash Handler] #4 0x00007f0f44b02e83 in QHashData::nextNode(QHashData::Node*) () at /usr/lib64/libQt5Core.so.5 #5 0x00007f0f443d11fa in QHash<QString, QHashDummyValue>::erase(QHash<QString, QHashDummyValue>::const_iterator) () at /usr/lib64/libKF5WidgetsAddons.so.5 #6 0x00007f0f443d05ea in KViewStateSerializerPrivate::restoreSelection() () at /usr/lib64/libKF5WidgetsAddons.so.5 #7 0x00007f0f443d0c99 in KViewStateSerializer::restoreSelection(QStringList const&) () at /usr/lib64/libKF5WidgetsAddons.so.5 #8 0x00007f0f443d0e15 in KViewStateSerializerPrivate::processPendingChanges() () at /usr/lib64/libKF5WidgetsAddons.so.5 #9 0x00007f0f443d0f63 in QtPrivate::QFunctorSlotObject<KViewStateSerializerPrivate::listenToPendingChanges()::{lambda(QModelIndex const&, int, int)#1}, 3, QtPrivate::List<QModelIndex const&, int, int>, void>::impl(int, QtPrivate::QSlotObjectBase*, QObject*, void**, bool*) () at /usr/lib64/libKF5WidgetsAddons.so.5 #10 0x00007f0f44ca81cd in void doActivate<false>(QObject*, int, void**) () at /usr/lib64/libQt5Core.so.5 #11 0x00007f0f44c2841e in QAbstractItemModel::rowsInserted(QModelIndex const&, int, int, QAbstractItemModel::QPrivateSignal) () at /usr/lib64/libQt5Core.so.5 #12 0x00007f0f44c30f8a in QAbstractItemModel::endInsertRows() () at /usr/lib64/libQt5Core.so.5 #13 0x00007f0f44c5414d in QSortFilterProxyModelPrivate::insert_source_items(QVector<int>&, QVector<int>&, QVector<int> const&, QModelIndex const&, Qt::Orientation, bool) () at /usr/lib64/libQt5Core.so.5 #14 0x00007f0f44c56b89 in QSortFilterProxyModelPrivate::source_items_inserted(QModelIndex const&, int, int, Qt::Orientation) () at /usr/lib64/libQt5Core.so.5 #15 0x00007f0f44c5980d in QSortFilterProxyModelPrivate::_q_sourceRowsInserted(QModelIndex const&, int, int) () at /usr/lib64/libQt5Core.so.5 #16 0x00007f0f44ca82dc in void doActivate<false>(QObject*, int, void**) () at /usr/lib64/libQt5Core.so.5 #17 0x00007f0f44c2841e in QAbstractItemModel::rowsInserted(QModelIndex const&, int, int, QAbstractItemModel::QPrivateSignal) () at /usr/lib64/libQt5Core.so.5 #18 0x00007f0f44c30f8a in QAbstractItemModel::endInsertRows() () at /usr/lib64/libQt5Core.so.5 #19 0x00007f0efc98841a in Akonadi::EntityTreeModelPrivate::collectionsFetched(QVector<Akonadi::Collection> const&) () at /usr/lib64/libKF5AkonadiCore.so.5 #20 0x00007f0f44ca82dc in void doActivate<false>(QObject*, int, void**) () at /usr/lib64/libQt5Core.so.5 #21 0x00007f0efc933402 in Akonadi::CollectionFetchJob::collectionsReceived(QVector<Akonadi::Collection> const&) () at /usr/lib64/libKF5AkonadiCore.so.5 #22 0x00007f0efc937103 in QtPrivate::QFunctorSlotObject<Akonadi::CollectionFetchJobPrivate::init()::{lambda()#1}, 0, QtPrivate::List<>, void>::impl(int, QtPrivate::QSlotObjectBase*, QObject*, void**, bool*) () at /usr/lib64/libKF5AkonadiCore.so.5 #23 0x00007f0f44ca81cd in void doActivate<false>(QObject*, int, void**) () at /usr/lib64/libQt5Core.so.5 #24 0x00007f0f44cac2ba in QTimer::timeout(QTimer::QPrivateSignal) () at /usr/lib64/libQt5Core.so.5 #25 0x00007f0f44ca023d in QObject::event(QEvent*) () at /usr/lib64/libQt5Core.so.5 #26 0x00007f0f4576302e in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib64/libQt5Widgets.so.5 #27 0x00007f0f44c75f88 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at /usr/lib64/libQt5Core.so.5 #28 0x00007f0f44cc50b1 in QTimerInfoList::activateTimers() () at /usr/lib64/libQt5Core.so.5 #29 0x00007f0f44cc5934 in timerSourceDispatch(_GSource*, int (*)(void*), void*) () at /usr/lib64/libQt5Core.so.5 #30 0x00007f0f3b48baa9 in g_main_context_dispatch () at /usr/lib64/libglib-2.0.so.0 #31 0x00007f0f3b48be68 in g_main_context_iterate.constprop () at /usr/lib64/libglib-2.0.so.0 #32 0x00007f0f3b48befc in g_main_context_iteration () at /usr/lib64/libglib-2.0.so.0 #33 0x00007f0f44cc5cb6 in QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib64/libQt5Core.so.5 #34 0x00007f0f44c74a6b in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib64/libQt5Core.so.5 #35 0x00007f0f44c7c8e6 in QCoreApplication::exec() () at /usr/lib64/libQt5Core.so.5 #36 0x000056294d75f066 in main () [Inferior 1 (process 674543) detached] The reporter indicates this bug may be a duplicate of or related to bug 415634, bug 468579.
