3v1n0, gtk-module-Handle-display-closing-gracefully.patch introduced regression!
Why are you setting d->object to NULL in on_object_disposed? By doing that you are introducing memory leak, no? Creating SoundEventData structure strong reference is added, it must be removed otherwise object will never get finalized!? I am attaching small test app that can be used to reproduce problem - it simply prints warning messages when GObject / GtkWindow is disposed and/or finalized. Basically looks like now canberra-gtk-module adds two extra refs that are not removed. Also with attached test app free_sound_event now is never called with d->object != NULL. ** Attachment added: "Test app" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1949200/+attachment/5606320/+files/test-gtk.c -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libcanberra in Ubuntu. https://bugs.launchpad.net/bugs/1949200 Title: gnome-shell crashed with SIGTRAP from error "Can't create a GtkStyleContext without a display connection" in gtk_style_context_init Status in gnome-shell package in Ubuntu: Won't Fix Status in libcanberra package in Ubuntu: Fix Released Bug description: GNOME Shell isn't meant to use GTK at all, but it's repeatedly crashing in GTK since the introduction of GNOME 40. https://errors.ubuntu.com/problem/45d4ce4e8f26828ab6993261e8a20208ecf261b0 https://errors.ubuntu.com/problem/e60359af65f32c18a4a6ccc93fd3469b0e675844 https://errors.ubuntu.com/problem/73a93ba578f68516e680373ae324db01336e8bad https://errors.ubuntu.com/problem/d69ccaf1379f588b04ecac2a6cc93b9be31100b4 This seems to be a result of Xwayland crashing and gnome-shell then trying to recover (and failing). Although gnome-shell shouldn't be using GTK, and Wayland sessions shouldn't be dependent on having an X11 server (Xwayland) available. Fixing either of those should resolve this. WORKAROUND: sudo apt remove libcanberra-gtk3-module TEST CASE: 1. Log into a Wayland session. 2. Open a Terminal. 3. $ xrandr # Just to ensure Xwayland starts 4. $ killall Xwayland Expected: gnome-shell still responds. Observed: gnome-shell freezes or exits. --- ProblemType: Crash DistroRelease: Ubuntu 22.04 Package: gnome-shell 40.5-1ubuntu2 ProcVersionSignature: Ubuntu 5.13.0-19.19-generic 5.13.14 Uname: Linux 5.13.0-19-generic x86_64 ApportVersion: 2.20.11-0ubuntu72 Architecture: amd64 CasperMD5CheckResult: pass CrashCounter: 1 CurrentDesktop: ubuntu:GNOME Date: Fri Oct 29 15:11:43 2021 DisplayManager: gdm3 ExecutablePath: /usr/bin/gnome-shell InstallationDate: Installed on 2021-10-27 (2 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Alpha amd64 (20211023) ProcCmdline: /usr/bin/gnome-shell ProcEnviron: LANG=nb_NO.UTF-8 LANGUAGE=nb_NO:nb:no_NO:no:nn_NO:nn:en PATH=(custom, no user) SHELL=/bin/bash XDG_RUNTIME_DIR=<set> RelatedPackageVersions: mutter-common 40.5-1ubuntu2 Signal: 5 SourcePackage: gnome-shell StacktraceTop: g_log_writer_default () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 g_log_structured_array () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 g_log_structured_standard () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 ??
