I have some apps installed from aur (arch users repository). When I search form some of them in the apps launcher, right click its entry and select "manage <app>", discover 5.13.4 opens and says "cannot open appstream://app.desktop". I close discover, plasma shows a crash notification. Some apps from aur that produces the crash: tixati torrent client etcher (to create bootable usb sticks) yarock music player vokoscreen (screen recorder) #0 0x00007ff89f39886b in raise () at /usr/lib/libc.so.6 #1 0x00007ff8a3b1229f in KCrash::defaultCrashHandler(int) () at /usr/lib/libKF5Crash.so.5 #2 0x00007ff89f3988f0 in <signal handler called> () at /usr/lib/libc.so.6 #3 0x00007ff89f39886b in raise () at /usr/lib/libc.so.6 #4 0x00007ff89f38340e in abort () at /usr/lib/libc.so.6 #5 0x00007ff899b21b76 in g_assertion_message () at /usr/lib/libglib-2.0.so.0 #6 0x00007ff899b21bdc in g_assertion_message_expr () at /usr/lib/libglib-2.0.so.0 #7 0x00007ff860d3d7d2 in () at /usr/lib/libostree-1.so.1 #8 0x00007ff861cc2b05 in g_object_unref () at /usr/lib/libgobject-2.0.so.0 #9 0x00007ff8622be174 in () at /usr/lib/libflatpak.so.0 #10 0x00007ff861cc2b05 in g_object_unref () at /usr/lib/libgobject-2.0.so.0 #11 0x00007ff8623052a7 in flatpak_installation_list_remote_refs_sync () at /usr/lib/libflatpak.so.0 #12 0x00007ff862305440 in flatpak_installation_list_installed_refs_for_update () at /usr/lib/libflatpak.so.0 #13 0x00007ff86278d181 in non-virtual thunk to QtConcurrent::RunFunctionTask<_GPtrArray*>::run() () at /usr/lib/qt/plugins/discover/flatpak-backend.so #14 0x00007ff89fb629f1 in () at /usr/lib/libQt5Core.so.5 #15 0x00007ff89fb6ab45 in () at /usr/lib/libQt5Core.so.5 #16 0x00007ff89bd39075 in start_thread () at /usr/lib/libpthread.so.0 #17 0x00007ff89f45a53f in clone () at /usr/lib/libc.so.6
