Bug ID: 423682 Summary: system settings segmentation fault in QtWaylandClient::QWaylandWindow::decoration when selecting activities and closing Product: systemsettings Version: 5.19.2 Platform: Fedora RPMs OS: Linux Status: REPORTED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: matthew.fagn...@utoronto.ca Target Milestone: --- Application: systemsettings5 (5.19.2) Qt Version: 5.14.2 Frameworks Version: 5.71.0 Operating System: Linux 5.8.0-0.rc3.1.fc33.x86_64 x86_64 Windowing system: Wayland Distribution: Fedora 33 (KDE Plasma Prerelease) -- Information about the crash: - What I was doing when the application crashed: I was using Plasma 5.19.2 on Wayland in a Fedora Rawhide KDE Plasma spin installation with KF 5.71.0, Qt 5.14.2. I started System Settings on Wayland. I selected Workspace Behavior > Activities. The left menus were black as I reported at https://bugs.kde.org/show_bug.cgi?id=418291 The main part of System Settings wasn't displaying normally. I closed System Settings. A segmentation fault in System Settings happened in QtWaylandClient::QWaylandWindow::decoration at qwaylandwindow.cpp:825. this=0x0 in QtWaylandClient::QWaylandWindow::decoration might indicate a null pointer dereference as the reason for the segmentation fault. qwaylandwindow.cpp:825 returns mWindowDecoration in QtWaylandClient::QWaylandWindow::decoration QWaylandAbstractDecoration *QWaylandWindow::decoration() const { return mWindowDecoration; } -- Backtrace: Application: System Settings (systemsettings5), signal: Segmentation fault [KCrash Handler] #4 QtWaylandClient::QWaylandWindow::decoration (this=0x0) at qwaylandwindow.cpp:825 #5 0x00007f31b8a01759 in QtWaylandClient::QWaylandShmBackingStore::windowDecoration (this=this@entry=0x5623ea6448c0) at qwaylandshmbackingstore.cpp:362 #6 0x00007f31b8a021c6 in QtWaylandClient::QWaylandShmBackingStore::resize (this=this@entry=0x5623ea6448c0, size=...) at qwaylandshmbackingstore.cpp:308 #7 0x00007f31b8a02301 in QtWaylandClient::QWaylandShmBackingStore::ensureSize (this=this@entry=0x5623ea6448c0) at qwaylandshmbackingstore.cpp:205 #8 0x00007f31b8a0233d in QtWaylandClient::QWaylandShmBackingStore::beginPaint (this=this@entry=0x5623ea6448c0, region=...) at qwaylandshmbackingstore.cpp:180 #9 0x00007f31cb08ddad in QBackingStore::beginPaint (this=0x5623ea6bc0c0, region=...) at ../../include/QtGui/5.14.2/QtGui/private/../../../../../src/gui/kernel/qhighdpiscaling_p.h:109 #10 0x00007f31cb4f3e0e in QWidgetRepaintManager::paintAndFlush (this=<optimized out>) at kernel/qwidgetrepaintmanager.cpp:984 #11 0x00007f31cb524a97 in QWidget::event (this=this@entry=0x5623ea4b5020, event=event@entry=0x5623ec3b09d0) at kernel/qwidget.cpp:8978 #12 0x00007f31cb633530 in QMainWindow::event (this=this@entry=0x5623ea4b5020, event=event@entry=0x5623ec3b09d0) at widgets/qmainwindow.cpp:1341 #13 0x00007f31cbfabf4d in KMainWindow::event (this=this@entry=0x5623ea4b5020, ev=ev@entry=0x5623ec3b09d0) at /usr/src/debug/kf5-kxmlgui-5.71.0-1.fc33.x86_64/src/kmainwindow.cpp:885 #14 0x00007f31cbfdac3d in KXmlGuiWindow::event (this=0x5623ea4b5020, ev=0x5623ec3b09d0) at /usr/src/debug/kf5-kxmlgui-5.71.0-1.fc33.x86_64/src/kxmlguiwindow.cpp:121 #15 0x00007f31cb4e3063 in QApplicationPrivate::notify_helper (this=<optimized out>, receiver=0x5623ea4b5020, e=0x5623ec3b09d0) at kernel/qapplication.cpp:3685 #16 0x00007f31caaabfc0 in QCoreApplication::notifyInternal2 (receiver=0x5623ea4b5020, event=0x5623ec3b09d0) at ../../include/QtCore/../../src/corelib/kernel/qobject.h:153 #17 0x00007f31caaaec47 in QCoreApplicationPrivate::sendPostedEvents (receiver=0x0, event_type=0, data=0x5623ea44b000) at kernel/qcoreapplication.cpp:1815 #18 0x00007f31caaf80a7 in postEventSourceDispatch (s=s@entry=0x5623ea466630) at kernel/qeventdispatcher_glib.cpp:277 #19 0x00007f31c882beaf in g_main_dispatch (context=0x5623ea47aa30) at ../glib/gmain.c:3309 #20 g_main_context_dispatch (context=0x5623ea47aa30) at ../glib/gmain.c:3974 #21 0x00007f31c882c238 in g_main_context_iterate (context=context@entry=0x5623ea47aa30, block=block@entry=1, dispatch=dispatch@entry=1, self=<optimized out>) at ../glib/gmain.c:4047 #22 0x00007f31c882c303 in g_main_context_iteration (context=0x5623ea47aa30, may_block=may_block@entry=1) at ../glib/gmain.c:4108 #23 0x00007f31caaf7b73 in QEventDispatcherGlib::processEvents (this=0x5623ea49d2f0, flags=...) at kernel/qeventdispatcher_glib.cpp:423 #24 0x00007f31caaaa91b in QEventLoop::exec (this=this@entry=0x7fff34ad2850, flags=..., flags@entry=...) at ../../include/QtCore/../../src/corelib/global/qflags.h:136 #25 0x00007f31caab25a6 in QCoreApplication::exec () at ../../include/QtCore/../../src/corelib/global/qflags.h:118 #26 0x00005623e98290cf in main (argc=<optimized out>, argv=0x7fff34ad2970) at /usr/src/debug/plasma-systemsettings-5.19.2-1.fc33.x86_64/app/main.cpp:168 [Inferior 1 (process 9398) detached] Reported using DrKonqi -- You are receiving this mail because: You are watching all bug changes.
