Application: dolphin (23.08.3) Qt Version: 5.15.11 Frameworks Version: 5.112.0 Operating System: Linux 6.6.2-zen1-1-zen x86_64 Windowing System: Wayland Distribution: Arch Linux DrKonqi: 5.27.9 [KCrashBackend] -- Information about the crash: Dolphin crashed when I tried to open a .mkv video file that had just been created (and was also still being written to). Dolphin itself was already open for about an hour and I had no issues opening any files before this one. In case it matters, thumbnail previews for videos were turned off. The crash does not seem to be reproducible. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault [KCrash Handler] #4 0x0000000000000020 in () #5 0x00007f760f2a8d24 in KItemListController::onRelease(QPointF const&, QFlags<Qt::KeyboardModifier>, QFlags<Qt::MouseButton>, bool) () at /usr/lib/libdolphinprivate.so.5 #6 0x00007f760f2a8e30 in KItemListController::mouseReleaseEvent(QGraphicsSceneMouseEvent*, QTransform const&) () at /usr/lib/libdolphinprivate.so.5 #7 0x00007f760f2ab0eb in KItemListController::processEvent(QEvent*, QTransform const&) () at /usr/lib/libdolphinprivate.so.5 #8 0x00007f760f2b142e in KItemListView::event(QEvent*) () at /usr/lib/libdolphinprivate.so.5 #9 0x00007f760dd788ff in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib/libQt5Widgets.so.5 #10 0x00007f760d09c168 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at /usr/lib/libQt5Core.so.5 #11 0x00007f760e095b20 in () at /usr/lib/libQt5Widgets.so.5 #12 0x00007f760e09a57a in () at /usr/lib/libQt5Widgets.so.5 #13 0x00007f760e09bb7e in QGraphicsScene::mouseReleaseEvent(QGraphicsSceneMouseEvent*) () at /usr/lib/libQt5Widgets.so.5 #14 0x00007f760e0a10c4 in QGraphicsScene::event(QEvent*) () at /usr/lib/libQt5Widgets.so.5 #15 0x00007f760dd788ff in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib/libQt5Widgets.so.5 #16 0x00007f760d09c168 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at /usr/lib/libQt5Core.so.5 #17 0x00007f760e0c955e in QGraphicsView::mouseReleaseEvent(QMouseEvent*) () at /usr/lib/libQt5Widgets.so.5 #18 0x00007f760ddaf1a1 in QWidget::event(QEvent*) () at /usr/lib/libQt5Widgets.so.5 #19 0x00007f760de5d9e3 in QFrame::event(QEvent*) () at /usr/lib/libQt5Widgets.so.5 #20 0x00007f760d099142 in QCoreApplicationPrivate::sendThroughObjectEventFilters(QObject*, QEvent*) () at /usr/lib/libQt5Core.so.5 #21 0x00007f760dd788ef in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib/libQt5Widgets.so.5 #22 0x00007f760dd7ddaf in QApplication::notify(QObject*, QEvent*) () at /usr/lib/libQt5Widgets.so.5 #23 0x00007f760d09c168 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at /usr/lib/libQt5Core.so.5 #24 0x00007f760dd7c0ea in QApplicationPrivate::sendMouseEvent(QWidget*, QMouseEvent*, QWidget*, QWidget*, QWidget**, QPointer<QWidget>&, bool, bool) () at /usr/lib/libQt5Widgets.so.5 #25 0x00007f760ddcceb5 in () at /usr/lib/libQt5Widgets.so.5 #26 0x00007f760ddcec07 in () at /usr/lib/libQt5Widgets.so.5 #27 0x00007f760dd788ff in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib/libQt5Widgets.so.5 #28 0x00007f760d09c168 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at /usr/lib/libQt5Core.so.5 #29 0x00007f760d54196c in QGuiApplicationPrivate::processMouseEvent(QWindowSystemInterfacePrivate::MouseEvent*) () at /usr/lib/libQt5Gui.so.5 #30 0x00007f760d52a6f5 in QWindowSystemInterface::sendWindowSystemEvents(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib/libQt5Gui.so.5 #31 0x00007f760a75ece5 in () at /usr/lib/libQt5WaylandClient.so.5 #32 0x00007f760b10df69 in () at /usr/lib/libglib-2.0.so.0 #33 0x00007f760b16c327 in () at /usr/lib/libglib-2.0.so.0 #34 0x00007f760b10c162 in g_main_context_iteration () at /usr/lib/libglib-2.0.so.0 #35 0x00007f760d0eaf9f in QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib/libQt5Core.so.5 #36 0x00007f760d09ae74 in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib/libQt5Core.so.5 #37 0x00007f760d09c313 in QCoreApplication::exec() () at /usr/lib/libQt5Core.so.5 #38 0x000055bef6365db8 in () #39 0x00007f760c845cd0 in () at /usr/lib/libc.so.6 #40 0x00007f760c845d8a in __libc_start_main () at /usr/lib/libc.so.6 #41 0x000055bef6366575 in () [Inferior 1 (process 2109) detached] Reported using DrKonqi
Hi, thank you for your bug report! Could you try to obtain debug symbols for your backtrace? There are detailed instructions at https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports In particular, on Arch Linux, if you reproduce it, I think you can just click Install Debug Symbols from Dr. Konqi.
Created attachment 163492 [details] Backtrace with debug symbols output of `bt full` within gdb.
The issue comes from here: ``` #6 0x00007f760f2a8d24 in KItemListController::onRelease(QPointF const&, QFlags<Qt::KeyboardModifier>, QFlags<Qt::MouseButton>, bool) (this=this@entry=0x55bef7a92600, pos=..., modifiers=..., modifiers@entry=..., buttons=buttons@entry=..., touch=touch@entry=false) at /usr/src/debug/dolphin/dolphin-23.08.3/src/kitemviews/kitemlistcontroller.cpp:1779 singleClickActivation = <optimized out> emitItemActivated = true isAboveSelectionToggle = <optimized out> controlPressed = <optimized out> shiftOrControlPressed = <optimized out> index = std::optional<int> = {[contained value] = 0} rubberBand = <optimized out> rubberBandRelease = <optimized out> ``` From src/kitemviews/kitemlistcontroller.cpp: ``` if (buttons & Qt::LeftButton) { bool emitItemActivated = true; if (m_view->isAboveExpansionToggle(index.value(), pos)) { const bool expanded = m_model->isExpanded(index.value()); m_model->setExpanded(index.value(), !expanded); Q_EMIT itemExpansionToggleClicked(index.value()); emitItemActivated = false; } else if (shiftOrControlPressed && m_selectionBehavior != SingleSelection) { // The mouse click should only update the selection, not trigger the item, except when // we are in single selection mode emitItemActivated = false; } else { #line 1779: const bool singleClickActivation = m_view->style()->styleHint(QStyle::SH_ItemView_ActivateItemOnSingleClick) || m_singleClickActivationEnforced; if (!singleClickActivation) { emitItemActivated = touch && !m_selectionMode; } else { // activate on single click only if we didn't come from a rubber band release emitItemActivated = !rubberBandRelease; } } ```` m_view seems like it could be null, or m_view->style(), both make little sense and should not be possible. Do you use the folder panel ? Do you use split view ? What is the style you are using ?
I don't use the folder panel or split view, though I had tabs to other folders open. I use the "details" view mode (with name, file size and modified date columns) and basically the only change I did to the style was add a "refresh view" (F5) button to the toolbar.
I was able to reproduce this again after a reboot by doing the following: opening Dolphin and minimizing it -> changing the menu transparency from opaque to transparent on Breeze's application style -> maximizing Dolphin and trying to open a file. After the first crash, I am not able to reproduce this again after doing these same steps on the same Plasma session.
