Application: plasma-discover (5.24.4) Qt Version: 5.15.3 Frameworks Version: 5.92.0 Operating System: Linux 5.15.0-27-generic x86_64 Windowing System: X11 Distribution: Ubuntu 22.04 LTS DrKonqi: 5.24.4 [KCrashBackend] -- Information about the crash: - What I was doing when the application crashed: I was connected to the desktop session running XRDP, via KRDC client. I opened up Discover, and it said it was fetching updates. I clicked around a bit in the GUI, as it seemed no updates were coming, and it crashed. I've seen it do this before, seemingly misbehave over RDP. The crash can be reproduced sometimes. -- Backtrace: Application: Discover (plasma-discover), signal: Segmentation fault [KCrash Handler] #4 FlatpakBackend::findSource (origin=..., installation=0x7fdbec005880, this=0x5628526adac0) at ./libdiscover/backends/FlatpakBackend/FlatpakBackend.cpp:114 #5 FlatpakBackend::getAppForInstalledRef (this=0x5628526adac0, installation=0x7fdbec005880, ref=0x7fdbe431dd90, freshResource=0x7ffeb3b953e7) at ./libdiscover/backends/FlatpakBackend/FlatpakBackend.cpp:357 #6 0x00007fdc046d325e in operator() (__closure=0x7fdbbc601430) at ./libdiscover/backends/FlatpakBackend/FlatpakBackend.cpp:1296 #7 QtPrivate::FunctorCall<QtPrivate::IndexesList<>, QtPrivate::List<>, void, FlatpakBackend::search(const AbstractResourcesBackend::Filters&)::<lambda()>::<lambda()> >::call (arg=<optimized out>, f=...) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qobjectdefs_impl.h:146 #8 QtPrivate::Functor<FlatpakBackend::search(const AbstractResourcesBackend::Filters&)::<lambda()>::<lambda()>, 0>::call<QtPrivate::List<>, void> (arg=<optimized out>, f=...) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qobjectdefs_impl.h:256 #9 QtPrivate::QFunctorSlotObject<FlatpakBackend::search(const AbstractResourcesBackend::Filters&)::<lambda()>::<lambda()>, 0, QtPrivate::List<>, void>::impl(int, QtPrivate::QSlotObjectBase *, QObject *, void **, bool *) (which=<optimized out>, this_=0x7fdbbc601420, r=<optimized out>, a=<optimized out>, ret=<optimized out>) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qobjectdefs_impl.h:443 #10 0x00007fdc7406a783 in QtPrivate::QSlotObjectBase::call (a=0x7ffeb3b954c0, r=0x5628526adac0, this=0x7fdbbc601420) at ../../include/QtCore/../../src/corelib/kernel/qobjectdefs_impl.h:398 #11 doActivate<false> (sender=0x7fdbbd3fd520, signal_index=4, argv=0x7ffeb3b954c0) at kernel/qobject.cpp:3886 #12 0x00007fdc74063a97 in QMetaObject::activate (sender=<optimized out>, m=<optimized out>, local_signal_index=<optimized out>, argv=<optimized out>) at kernel/qobject.cpp:3946 #13 0x00007fdc73e500f5 in QFutureWatcherBase::event (this=<optimized out>, event=0x7fdbe4697130) at thread/qfuturewatcher.cpp:334 #14 0x00007fdc751d1713 in QApplicationPrivate::notify_helper (this=<optimized out>, receiver=0x7fdbbd3fd520, e=0x7fdbe4697130) at kernel/qapplication.cpp:3637 #15 0x00007fdc74032e2a in QCoreApplication::notifyInternal2 (receiver=0x7fdbbd3fd520, event=0x7fdbe4697130) at kernel/qcoreapplication.cpp:1064 #16 0x00007fdc74035f17 in QCoreApplicationPrivate::sendPostedEvents (receiver=0x0, event_type=0, data=0x562851e02480) at kernel/qcoreapplication.cpp:1821 #17 0x00007fdc7408ca57 in postEventSourceDispatch (s=0x562851ecfc80) at kernel/qeventdispatcher_glib.cpp:277 #18 0x00007fdc72929d1b in g_main_dispatch (context=0x7fdc68005010) at ../../../glib/gmain.c:3417 #19 g_main_context_dispatch (context=0x7fdc68005010) at ../../../glib/gmain.c:4135 #20 0x00007fdc7297e6f8 in g_main_context_iterate.constprop.0 (context=context@entry=0x7fdc68005010, block=block@entry=1, dispatch=dispatch@entry=1, self=<optimized out>) at ../../../glib/gmain.c:4211 #21 0x00007fdc729273c3 in g_main_context_iteration (context=0x7fdc68005010, may_block=1) at ../../../glib/gmain.c:4276 #22 0x00007fdc7408c0a8 in QEventDispatcherGlib::processEvents (this=0x562851ed5a10, flags=...) at kernel/qeventdispatcher_glib.cpp:423 #23 0x00007fdc7403174b in QEventLoop::exec (this=this@entry=0x7ffeb3b958a0, flags=..., flags@entry=...) at ../../include/QtCore/../../src/corelib/global/qflags.h:69 #24 0x00007fdc74039ce4 in QCoreApplication::exec () at ../../include/QtCore/../../src/corelib/global/qflags.h:121 #25 0x00007fdc7440ee10 in QGuiApplication::exec () at kernel/qguiapplication.cpp:1867 #26 0x00007fdc751d1689 in QApplication::exec () at kernel/qapplication.cpp:2829 #27 0x0000562851bdb638 in main (argc=<optimized out>, argv=<optimized out>) at ./discover/main.cpp:217 [Inferior 1 (process 870014) detached] Possible duplicates by query: bug 453440, bug 452999, bug 452469, bug 450949, bug 450401.
