Application: kcmshell5 (5.19.0) Qt Version: 5.15.0 Frameworks Version: 5.71.0 Operating System: Linux 5.7.1-1-default x86_64 Windowing system: X11 Distribution: "openSUSE Tumbleweed" -- Information about the crash: - What I was doing when the application crashed: 1) Open Application (tried with several) 2) Access WIndow menu with Alt+F3 or by right clicking on the titlebar 3) Select "More Actions" 4) Select "Configure Window Manager" ----> Crash notification appears instead of desired configuration window. Other context menu options (Special Windows Settings etc) work fine. The same settings window behaves fine when accessed through the KDE settings or by accessing "Window Rules" from KRunner. The crash can be reproduced every time. -- Backtrace: Application: System Settings Module (kcmshell5), signal: Segmentation fault [KCrash Handler] #4 0x00007f9aa5a4ab97 in std::__atomic_base<QThreadData*>::load (__m=std::memory_order_acquire, this=0x38) at /usr/include/c++/10/bits/atomic_base.h:741 #5 std::atomic<QThreadData*>::load (__m=std::memory_order_acquire, this=0x38) at /usr/include/c++/10/atomic:523 #6 QAtomicOps<QThreadData*>::loadAcquire<QThreadData*> (_q_value=...) at ../../include/QtCore/../../src/corelib/thread/qatomic_cxx11.h:251 #7 QBasicAtomicPointer<QThreadData>::loadAcquire (this=0x38) at ../../include/QtCore/../../src/corelib/thread/qbasicatomic.h:255 #8 QBasicAtomicPointer<QThreadData>::operator QThreadData* (this=0x38) at ../../include/QtCore/../../src/corelib/thread/qbasicatomic.h:251 #9 QObjectPrivate::setParent_helper (this=0x55efca8f8670, o=0x55efca8f84d0) at kernel/qobject.cpp:2157 #10 0x00007f9a933514ff in KWinOptionsSettings::KWinOptionsSettings (this=<optimized out>, parent=<optimized out>, this=<optimized out>, parent=<optimized out>) at /usr/src/debug/kwin5-5.19.0-1.1.x86_64/build/kcmkwin/kwinoptions/kwinoptions_settings.cpp:9 #11 0x00007f9a9334ed94 in KFocusConfigStandalone::KFocusConfigStandalone (parent=0x55efca803990, this=0x55efca8f84d0) at /usr/src/debug/kwin5-5.19.0-1.1.x86_64/kcmkwin/kwinoptions/main.cpp:44 #12 KPluginFactory::createInstance<KFocusConfigStandalone, QWidget> (parentWidget=<optimized out>, parent=<optimized out>, args=...) at /usr/include/KF5/KCoreAddons/kpluginfactory.h:520 #13 0x00007f9aa6bf9c52 in KPluginFactory::create (this=this@entry=0x55efca8d46e0, iface=0x7f9aa52bb298 "KCModule", parentWidget=parentWidget@entry=0x0, parent=parent@entry=0x55efca803990, args=..., keyword=...) at /usr/src/debug/kcoreaddons-5.71.0-1.1.x86_64/src/lib/plugin/kpluginfactory.cpp:133 #14 0x00007f9aa6f185dd in KPluginFactory::create<KCModule> (parentWidget=0x0, args=..., keyword=..., parent=0x55efca803990, this=0x55efca8d46e0) at /usr/include/KF5/KCoreAddons/kpluginfactory.h:567 #15 KService::createInstance<KCModule> (parentWidget=0x0, error=0x7ffd8d50e788, args=..., parent=0x55efca803990, this=0x55efca274450) at /usr/include/KF5/KService/kservice.h:557 #16 KService::createInstance<KCModule> (error=0x7ffd8d50e788, args=..., parent=0x55efca803990, this=0x55efca274450) at /usr/include/KF5/KService/kservice.h:532 #17 KCModuleLoader::loadModule (mod=..., report=report@entry=KCModuleLoader::Inline, parent=0x55efca803990, args=...) at /usr/src/debug/kcmutils-5.71.0-1.1.x86_64/src/kcmoduleloader.cpp:120 #18 0x00007f9aa6f18fa4 in KCModuleProxyPrivate::loadModule (this=this@entry=0x55efca8133b0) at /usr/src/debug/kcmutils-5.71.0-1.1.x86_64/src/kcmoduleproxy.cpp:94 #19 0x00007f9aa6f19638 in KCModuleProxy::realModule (this=this@entry=0x55efca803990) at /usr/src/debug/kcmutils-5.71.0-1.1.x86_64/src/kcmoduleproxy.cpp:67 #20 0x00007f9aa6f19ac2 in KCMultiDialog::addModule (this=0x7f9a940086a0, moduleInfo=..., parentItem=0x0, args=...) at /usr/src/debug/kcmutils-5.71.0-1.1.x86_64/src/kcmultidialog.cpp:496 #21 0x000055efc8e73ee0 in main (_argc=<optimized out>, _argv=<optimized out>) at /usr/include/qt5/QtCore/qbasicatomic.h:118 [Inferior 1 (process 24696) detached]
