Triaging to xdg-desktop-portal (the reported item that is crashing here) (In reply to Rex Dieter from comment #1) > Triaging to xdg-desktop-portal (the reported item that is crashing here) OK thanks. I ran xdg-desktop-portal under valgrind by editing /usr/lib/systemd/user/xdg-desktop-portal.service to have a line like ExecStart=valgrind /usr/libexec/xdg-desktop-portal and rebooting. I ran krfb from konsole. An invalid write and invalid read were found by valgrind in UnknownInlinedFun at screen-cast.c:587-589 in xdg-desktop-portal-1.12.1-2.fc36.x86_64 which might've been an out-of-bounds write and read given messages like "Address 0x1a573970 is 0 bytes after a block of size 256 alloc'd" ==2350== Thread 7 pool-/usr/libex: ==2350== Invalid write of size 4 ==2350== at 0x14C2EA: UnknownInlinedFun (screen-cast.c:587) ==2350== by 0x14C2EA: handle_select_sources (screen-cast.c:785) ==2350== by 0x4FB2745: ffi_call_unix64 (unix64.S:105) ==2350== by 0x4FAF4D1: ffi_call_int.lto_priv.0 (ffi64.c:672) ==2350== by 0x4B70082: g_cclosure_marshal_generic (gclosure.c:1534) ==2350== by 0x4B69E5F: g_closure_invoke (gclosure.c:830) ==2350== by 0x4B96884: signal_emit_unlocked_R.isra.0 (gsignal.c:3783) ==2350== by 0x16BB6A: _xdp_screen_cast_skeleton_handle_method_call (xdp-dbus.c:37045) ==2350== by 0x4A9FF6A: dispatch_in_thread_func (gdbusinterfaceskeleton.c:540) ==2350== by 0x4A2DFB2: g_task_thread_pool_thread (gtask.c:1434) ==2350== by 0x4C36EF1: g_thread_pool_thread_proxy.lto_priv.0 (gthreadpool.c:354) ==2350== by 0x4C344D1: g_thread_proxy (gthread.c:827) ==2350== by 0x4DA4016: start_thread (pthread_create.c:442) ==2350== Address 0x1a573970 is 0 bytes after a block of size 256 alloc'd ==2350== at 0x484586F: malloc (vg_replace_malloc.c:381) ==2350== by 0x4C0F498: g_malloc (gmem.c:125) ==2350== by 0x4C27DA5: g_slice_alloc (gslice.c:1072) ==2350== by 0x4C29DEC: g_slice_alloc0 (gslice.c:1098) ==2350== by 0x4B92236: g_type_create_instance (gtype.c:1901) ==2350== by 0x4B79FA7: g_object_new_internal (gobject.c:2011) ==2350== by 0x4B7B75C: g_object_new_valist (gobject.c:2355) ==2350== by 0x49F705D: g_initable_new_valist (ginitable.c:244) ==2350== by 0x49F713C: g_initable_new (ginitable.c:162) ==2350== by 0x147D29: UnknownInlinedFun (remote-desktop.c:160) ==2350== by 0x147D29: handle_create_session.lto_priv.1 (remote-desktop.c:272) ==2350== by 0x4FB2745: ffi_call_unix64 (unix64.S:105) ==2350== by 0x4FAF4D1: ffi_call_int.lto_priv.0 (ffi64.c:672) ==2350== ==2350== Invalid read of size 4 ==2350== at 0x14C315: UnknownInlinedFun (screen-cast.c:589) ==2350== by 0x14C315: handle_select_sources (screen-cast.c:785) ==2350== by 0x4FB2745: ffi_call_unix64 (unix64.S:105) ==2350== by 0x4FAF4D1: ffi_call_int.lto_priv.0 (ffi64.c:672) ==2350== by 0x4B70082: g_cclosure_marshal_generic (gclosure.c:1534) ==2350== by 0x4B69E5F: g_closure_invoke (gclosure.c:830) ==2350== by 0x4B96884: signal_emit_unlocked_R.isra.0 (gsignal.c:3783) ==2350== by 0x16BB6A: _xdp_screen_cast_skeleton_handle_method_call (xdp-dbus.c:37045) ==2350== by 0x4A9FF6A: dispatch_in_thread_func (gdbusinterfaceskeleton.c:540) ==2350== by 0x4A2DFB2: g_task_thread_pool_thread (gtask.c:1434) ==2350== by 0x4C36EF1: g_thread_pool_thread_proxy.lto_priv.0 (gthreadpool.c:354) ==2350== by 0x4C344D1: g_thread_proxy (gthread.c:827) ==2350== by 0x4DA4016: start_thread (pthread_create.c:442) ==2350== Address 0x1a573970 is 0 bytes after a block of size 256 alloc'd ==2350== at 0x484586F: malloc (vg_replace_malloc.c:381) ==2350== by 0x4C0F498: g_malloc (gmem.c:125) ==2350== by 0x4C27DA5: g_slice_alloc (gslice.c:1072) ==2350== by 0x4C29DEC: g_slice_alloc0 (gslice.c:1098) ==2350== by 0x4B92236: g_type_create_instance (gtype.c:1901) ==2350== by 0x4B79FA7: g_object_new_internal (gobject.c:2011) ==2350== by 0x4B7B75C: g_object_new_valist (gobject.c:2355) ==2350== by 0x49F705D: g_initable_new_valist (ginitable.c:244) ==2350== by 0x49F713C: g_initable_new (ginitable.c:162) ==2350== by 0x147D29: UnknownInlinedFun (remote-desktop.c:160) ==2350== by 0x147D29: handle_create_session.lto_priv.1 (remote-desktop.c:272) ==2350== by 0x4FB2745: ffi_call_unix64 (unix64.S:105) ==2350== by 0x4FAF4D1: ffi_call_int.lto_priv.0 (ffi64.c:672) ==2350== ==2350== xdg-desktop-portal didn't crash under valgrind, but I only ran it a couple times with the same invalid writes and reads shown.

(In reply to Adam Williamson from comment #9) > Re-opening and nominating as Final FE, because fixing startup of krfb would > be good for the KDE live (it's a default app). Thanks. xdg-desktop-portal from xdg-desktop-portal-1.12.4-1.fc36 hasn't crashed when I've run krfb from konsole several times. krfb still doesn't start from the Application Launcher menu as reported at https://bugzilla.redhat.com/show_bug.cgi?id=2060441 Rex reported that problem with a way to fix it by removing %i from Exec=krfb -qwindowtitle %c %i in org.kde.krfb.desktop at https://bugs.kde.org/show_bug.cgi?id=451140 +5 in https://pagure.io/fedora-qa/blocker-review/issue/796 , marking accepted.

Description of problem: I started krfb from konsole in Plasma 5.24.2 on Wayland in a Fedora 36 KDE Plasma installation. I noticed that krfb didn't appear after trying to start it from the Application Launcher menu. xdg-desktop-portal segmentation faulted in magazine_chain_pop_head at ../glib/gslice.c:579 in glib2-2.71.2-1.fc36.x86_64 sometimes when starting krfb with the following trace. Core was generated by `/usr/libexec/xdg-desktop-portal'. Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00007fe40a194f51 in magazine_chain_pop_head (magazine_chunks=<optimized out>) at ../glib/gslice.c:579 579 ChunkLink *chunk = (*magazine_chunks)->data; [Current thread is 1 (Thread 0x7fe3fb689640 (LWP 16331))] (gdb) bt #0 0x00007fe40a194f51 in magazine_chain_pop_head (magazine_chunks=<optimized out>) at ../glib/gslice.c:579 #1 magazine_chain_prepare_fields (magazine_chunks=0x7fe300000000) at ../glib/gslice.c:661 #2 magazine_cache_push_magazine (ix=14, magazine_chunks=0x7fe3d0008110, count=5) at ../glib/gslice.c:735 #3 0x00007fe40a1950f6 in private_thread_memory_cleanup (data=0x7fe3d00008e0) at ../glib/gslice.c:821 #4 0x00007fe409f89181 in __GI___nptl_deallocate_tsd () at nptl_deallocate_tsd.c:73 #5 __GI___nptl_deallocate_tsd () at nptl_deallocate_tsd.c:22 #6 0x00007fe409f8be98 in start_thread (arg=<optimized out>) at pthread_create.c:453 #7 0x00007fe40a0116d0 in clone3 () at ../sysdeps/unix/sysv/linux/x86_64/clone3.S:81 The journal from when one of the crashes happened follows.

I usually clicked to remove the check mark beside Enable Screen Sharing though I don't know if that is necessary for the crash to happen. Version-Release number of selected component (if applicable): krfb-21.12.2-1.fc36.x86_64 glib2-2.71.2-1.fc36.x86_64 xdg-desktop-portal-1.12.1-2.fc36.x86_64 plasma-workspace-5.24.2-2.fc36.x86_64 kf5-plasma-5.91.0-1.fc36.x86_64 qt5-qtbase-5.15.2-33.fc36.x86_64 How reproducible: xdg-desktop-portal crashed 4/6 times when starting krfb. Steps to Reproduce: 1. Boot a Fedora 36 KDE Plasma installation updated to 2022-3-4 with updates-testing enabled 2. Log in to Plasma on Wayland 3. Start Konsole 4. Run krfb in Konsole 5. click to remove the check mark beside Enable Screen Sharing. I'm unsure if this step is necessary. Actual results: Starting krfb from konsole sometimes resulted in a crash of xdg-desktop-portal Expected results: xdg-desktop-portal wouldn't crash. Additional info:
