Application: partitionmanager (4.2.0) Qt Version: 5.15.2 Frameworks Version: 5.78.0 Operating System: Linux 5.10.13-200.fc33.x86_64 x86_64 Windowing system: X11 Distribution: Fedora 33 (KDE Plasma) -- Information about the crash: - What I was doing when the application crashed: Launched KDE Partition Manager. The program loads with all blanks windows for each GUI pane and then proceeds to rapidly flicker a blue rectangle around the "Please select a device" window while displaying a spinning loading cursor indefinitely. Clicking on menu items does nothing and only clicking the X works to close the program with a crash. - Custom settings of the application: Before when KDE Partition Manager would load successfully I had not yet set Active Backend to KDE Partition Manager Dummy Backend. The crash can be reproduced every time. -- Backtrace: Application: KDE Partition Manager (partitionmanager), signal: Aborted [KCrash Handler] #4 0x00007f0d4af069d5 in raise () from /lib64/libc.so.6 #5 0x00007f0d4aeef8a4 in abort () from /lib64/libc.so.6 #6 0x00007f0d4b32d48f in QMessageLogger::fatal(char const*, ...) const () from /lib64/libQt5Core.so.5 #7 0x00007f0d4b32dcfb in QThread::~QThread() [clone .cold] () from /lib64/libQt5Core.so.5 #8 0x00007f0d4caf6f47 in DeviceScanner::~DeviceScanner() () from /lib64/libkpmcore.so.10 #9 0x00007f0d4b52593a in QObjectPrivate::deleteChildren() () from /lib64/libQt5Core.so.5 #10 0x00007f0d4bfcf246 in QWidget::~QWidget() () from /lib64/libQt5Widgets.so.5 #11 0x000056252967c5d4 in MainWindow::~MainWindow() () #12 0x00007f0d4b525b21 in QObject::event(QEvent*) () from /lib64/libQt5Core.so.5 #13 0x00007f0d4ca74dbd in KXmlGuiWindow::event(QEvent*) () from /lib64/libKF5XmlGui.so.5 #14 0x00007f0d4bf92ec3 in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /lib64/libQt5Widgets.so.5 #15 0x00007f0d4b4fdbd8 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () from /lib64/libQt5Core.so.5 #16 0x00007f0d4b5008c7 in QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) () from /lib64/libQt5Core.so.5 #17 0x00007f0d4b54ac27 in postEventSourceDispatch(_GSource*, int (*)(void*), void*) () from /lib64/libQt5Core.so.5 #18 0x00007f0d49d79a5f in g_main_context_dispatch () from /lib64/libglib-2.0.so.0 #19 0x00007f0d49dcba58 in g_main_context_iterate.constprop () from /lib64/libglib-2.0.so.0 #20 0x00007f0d49d76e33 in g_main_context_iteration () from /lib64/libglib-2.0.so.0 #21 0x00007f0d4b54a6f3 in QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () from /lib64/libQt5Core.so.5 #22 0x00007f0d4b4fc57b in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () from /lib64/libQt5Core.so.5 #23 0x00007f0d4b5041b4 in QCoreApplication::exec() () from /lib64/libQt5Core.so.5 #24 0x0000562529677d7f in main () [Inferior 1 (process 3558) detached] Possible duplicates by query: bug 430799, bug 430393, bug 424911, bug 423951, bug 423132.
