Bug ID: 434779 Summary: ksysguard segmentation faulted in QWidget::focusPolicy when closing Product: ksysguard Version: 5.21.3 Platform: Fedora RPMs OS: Linux Status: REPORTED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: ksysguard-b...@kde.org Reporter: matthew.fagn...@utoronto.ca CC: plasma-b...@kde.org Target Milestone: --- Application: ksysguard (5.21.3) Qt Version: 5.15.2 Frameworks Version: 5.80.0 Operating System: Linux 5.11.8-300.fc34.x86_64 x86_64 Windowing System: Wayland Drkonqi Version: 5.21.3 Distribution: Fedora 34 (KDE Plasma Prerelease) -- Information about the crash: - What I was doing when the application crashed: I opened ksysguard in Plasma 5.21.3 on Wayland in a Fedora 34 KDE Plasma installation. I sorted by the process name by clicking on the Name column header. I scrolled down through the processes. I closed ksysguard. ksysguard segmentation faulted in QWidget::focusPolicy at kernel/qwidget.cpp:7606 in qt5-qtbase-5.15.2-15.fc34.x86_64 when closing. This crash usually hasn't happened when closing ksysguard. The reporter is unsure if this crash is reproducible. -- Backtrace: Application: System Monitor (ksysguard), signal: Segmentation fault [KCrash Handler] #4 0x00007f8bea556918 in QWidget::focusPolicy (this=0x55ea13299900) at kernel/qwidget.cpp:7606 #5 0x00007f8bea665022 in QLabelPrivate::needTextControl (this=0x55ea1302a980) at widgets/qlabel_p.h:99 #6 QLabel::setText (this=0x55ea12d3ebf0, text=...) at widgets/qlabel.cpp:344 #7 0x00007f8beb453f2a in TopLevel::answerReceived (this=0x55ea12d1c340, id=<optimized out>, answerList=...) at /usr/src/debug/ksysguard-5.21.3-1.fc34.x86_64/gui/ksysguard.cpp:466 #8 0x00007f8beb1a655e in KSGRD::SensorAgent::processAnswer (this=0x55ea130ceef0, buf=<optimized out>, buflen=<optimized out>) at /usr/src/debug/libksysguard-5.21.3.1-1.fc34.x86_64/ksgrd/SensorAgent.cpp:306 #9 0x00007f8beb1aa520 in KSGRD::SensorShellAgent::msgRcvd (this=0x55ea130ceef0) at /usr/src/debug/libksysguard-5.21.3.1-1.fc34.x86_64/ksgrd/SensorShellAgent.cpp:93 #10 0x00007f8be99374b0 in QtPrivate::QSlotObjectBase::call (a=0x7ffc54683100, r=<optimized out>, this=0x55ea13034d90) at ../../include/QtCore/../../src/corelib/kernel/qobjectdefs_impl.h:398 #11 doActivate<false> (sender=0x55ea12fd73e0, signal_index=15, argv=0x7ffc54683100) at kernel/qobject.cpp:3886 #12 0x00007f8be99319e7 in QMetaObject::activate (sender=<optimized out>, m=m@entry=0x7f8be9bca060 <QProcess::staticMetaObject>, local_signal_index=local_signal_index@entry=6, argv=argv@entry=0x7ffc54683100) at kernel/qobject.cpp:3946 #13 0x00007f8be9898a31 in QProcess::readyReadStandardOutput (this=<optimized out>, _t1=...) at .moc/moc_qprocess.cpp:367 #14 0x00007f8be989c42d in QProcessPrivate::tryReadFromChannel (this=0x55ea13037c70, channel=0x55ea13037d80) at io/qprocess.cpp:1073 #15 0x00007f8be989c8f5 in QProcessPrivate::_q_canReadStandardError (this=<optimized out>) at io/qprocess.cpp:1092 #16 QProcess::qt_static_metacall (_o=<optimized out>, _c=<optimized out>, _id=<optimized out>, _a=0x7ffc546832a0) at .moc/moc_qprocess.cpp:210 #17 0x00007f8be99374fd in doActivate<false> (sender=0x55ea13077d50, signal_index=3, argv=0x7ffc546832a0) at kernel/qobject.cpp:3898 #18 0x00007f8be99319e7 in QMetaObject::activate (sender=sender@entry=0x55ea13077d50, m=m@entry=0x7f8be9bcc440 <QSocketNotifier::staticMetaObject>, local_signal_index=local_signal_index@entry=0, argv=argv@entry=0x7ffc546832a0) at kernel/qobject.cpp:3946 #19 0x00007f8be9939b3a in QSocketNotifier::activated (this=this@entry=0x55ea13077d50, _t1=..., _t2=<optimized out>, _t3=...) at .moc/moc_qsocketnotifier.cpp:178 #20 0x00007f8be993a2d4 in QSocketNotifier::event (this=0x55ea13077d50, e=<optimized out>) at kernel/qsocketnotifier.cpp:302 #21 0x00007f8bea52de73 in QApplicationPrivate::notify_helper (this=<optimized out>, receiver=0x55ea13077d50, e=0x7ffc546833c0) at kernel/qapplication.cpp:3632 #22 0x00007f8be9906f48 in QCoreApplication::notifyInternal2 (receiver=0x55ea13077d50, event=0x7ffc546833c0) at kernel/qcoreapplication.cpp:1063 #23 0x00007f8be995417f in socketNotifierSourceDispatch (source=0x55ea12d416a0) at kernel/qeventdispatcher_glib.cpp:107 #24 0x00007f8be04e5377 in g_main_dispatch (context=0x55ea12d3f620) at ../glib/gmain.c:3337 #25 g_main_context_dispatch (context=0x55ea12d3f620) at ../glib/gmain.c:4055 #26 0x00007f8be05392c8 in g_main_context_iterate.constprop.0 (context=context@entry=0x55ea12d3f620, block=block@entry=1, dispatch=dispatch@entry=1, self=<optimized out>) at ../glib/gmain.c:4131 #27 0x00007f8be04e2ab3 in g_main_context_iteration (context=0x55ea12d3f620, may_block=1) at ../glib/gmain.c:4196 #28 0x00007f8be99536f8 in QEventDispatcherGlib::processEvents (this=0x55ea12d41ca0, flags=...) at kernel/qeventdispatcher_glib.cpp:423 #29 0x00007f8be99059b2 in QEventLoop::exec (this=this@entry=0x7ffc54683630, flags=..., flags@entry=...) at ../../include/QtCore/../../src/corelib/global/qflags.h:69 #30 0x00007f8be990d544 in QCoreApplication::exec () at ../../include/QtCore/../../src/corelib/global/qflags.h:121 #31 0x00007f8be9ecc5d0 in QGuiApplication::exec () at kernel/qguiapplication.cpp:1860 #32 0x00007f8bea52dde9 in QApplication::exec () at kernel/qapplication.cpp:2824 #33 0x00007f8beb453a06 in kdemain (argc=<optimized out>, argv=<optimized out>) at /usr/src/debug/ksysguard-5.21.3-1.fc34.x86_64/gui/ksysguard.cpp:627 #34 0x00007f8beb23fb75 in __libc_start_main (main=0x55ea11979070 <main(int, char**)>, argc=1, argv=0x7ffc54683888, init=<optimized out>, fini=<optimized out>, rtld_fini=<optimized out>, stack_end=0x7ffc54683878) at ../csu/libc-start.c:332 #35 0x000055ea119790ae in _start () [Inferior 1 (process 1879) detached] The reporter indicates this bug may be a duplicate of or related to bug 400499.
