Application: plasma-discover (6.0.2) Qt Version: 6.6.2 Frameworks Version: 6.0.0 Operating System: Linux 6.7.9-arch1-1 x86_64 Windowing System: Wayland Distribution: "Arch Linux" DrKonqi: 6.0.2 [CoredumpBackend] -- Information about the crash: Discover crashes whenever I search for something. I only really use it for flatpaks. It might not be able to access the arch repo side of things and crashes because of that. Just a guess, it could be anything and I can't make sense of the backtrace. The crash can be reproduced every time. -- Backtrace (Reduced): #5 0x000079897ff7ed4a in KNSCore::ResultsStream::fetch (this=0x6418ad87fd10) at /usr/src/debug/knewstuff/knewstuff-6.0.0/src/core/resultsstream.cpp:70 #6 0x00007989b4590ca9 in QtPrivate::QSlotObjectBase::call (a=0x7ffc8884dd68, r=0x6418ad87fd10, this=0x6418a88c7530, this=<optimized out>, r=<optimized out>, a=<optimized out>) at /usr/src/debug/qt6-base/qtbase-everywhere-src-6.6.2/src/corelib/kernel/qobjectdefs_impl.h:433 #7 doActivate<false> (sender=0x6418a8d68130, signal_index=4, argv=0x7ffc8884dd68) at /usr/src/debug/qt6-base/qtbase-everywhere-src-6.6.2/src/corelib/kernel/qobject.cpp:4039 #8 0x00007989b4590ca9 in QtPrivate::QSlotObjectBase::call (a=0x7ffc8884de48, r=0x6418a8d68130, this=0x6418a914f6a0, this=<optimized out>, r=<optimized out>, a=<optimized out>) at /usr/src/debug/qt6-base/qtbase-everywhere-src-6.6.2/src/corelib/kernel/qobjectdefs_impl.h:433 #9 doActivate<false> (sender=0x6418a9201d30, signal_index=4, argv=0x7ffc8884de48) at /usr/src/debug/qt6-base/qtbase-everywhere-src-6.6.2/src/corelib/kernel/qobject.cpp:4039 Reported using DrKonqi

Can confirm this. I found that it only happens for me if I have "Home" selected when starting the search. If I select "All Applications" and then search, it works fine without crashing. Like for Tammes, I only use Discover for Flathub, since my package manager does not support appstream. So it seems likely that it's related to that.
I can also confirm this bug on KDE Neon. The workaround from Bernd works for me as well. Here's the output if I start Discover from the terminal: $ plasma-discover libs QList("/usr/lib/x86_64-linux-gnu/qt6/plugins", "/usr/bin") org.kde.plasma.libdiscover: OdrsReviewsBackend: Fetch ratings: false adding empty sources model QStandardItemModel(0x5571fc2e4420) qt.qml.typeresolution.cycle: Cyclic dependency detected between "qrc:/qt/qml/org/kde/desktop/private/TextFieldContextMenu.qml" and "qrc:/qt/qml/org/kde/desktop/MenuItem.qml" qrc:/qt/qml/org/kde/discover/qml/DiscoverWindow.qml:330:5: QML OverlaySheet: Binding loop detected for property "implicitHeight" qrc:/qt/qml/org/kde/discover/qml/BrowsingPage.qml:17:1: QML BrowsingPage: Created graphical object was not placed in the graphics scene.
