Package: gnome-shell Version: 3.30.0-1 Severity: important Dear Maintainer,
Upon upgrading to gnome-shell 3.30, I am experiencing frequent crashes of gnome-shell. This is the stack trace I get: Sep 06 12:18:56 bolt systemd-coredump[4691]: Process 3649 (gnome-shell) of user 1000 dumped core. Stack trace of thread 3649: #0 0x00007f1c8765c77b raise (libpthread.so.0) #1 0x0000563045848e2b n/a (gnome-shell) #2 0x00007f1c8765c8e0 __restore_rt (libpthread.so.0) #3 0x00007f1c874c2f3b __GI_raise (libc.so.6) #4 0x00007f1c874c42f1 __GI_abort (libc.so.6) #5 0x00007f1c8860fdd3 n/a (libglib-2.0.so.0) #6 0x00007f1c8866938a g_assertion_message_expr (libglib-2.0.so.0) #7 0x00007f1c87394ac9 n/a (libgdk-3.so.0) #8 0x00007f1c876ed12b n/a (libmutter-3.so.0) #9 0x00007f1c88721b6d g_closure_invoke (libgobject-2.0.so.0) #10 0x00007f1c887348f3 n/a (libgobject-2.0.so.0) #11 0x00007f1c8873d882 g_signal_emit_valist (libgobject-2.0.so.0) #12 0x00007f1c8873e3a4 g_signal_emit_by_name (libgobject-2.0.so.0) #13 0x00007f1c87877198 n/a (libmutter-clutter-3.so) #14 0x00007f1c878a3314 n/a (libmutter-clutter-3.so) #15 0x00007f1c87870b12 clutter_x11_handle_event (libmutter-clutter-3.so) #16 0x00007f1c876e9753 n/a (libmutter-3.so.0) #17 0x00007f1c88641c3e g_main_context_dispatch (libglib-2.0.so.0) #18 0x00007f1c88641ed8 n/a (libglib-2.0.so.0) #19 0x00007f1c886421d2 g_main_loop_run (libglib-2.0.so.0) #20 0x00007f1c87718fcc meta_run (libmutter-3.so.0) #21 0x0000563045848782 n/a (gnome-shell) #22 0x00007f1c874afb17 __libc_start_main (libc.so.6) #23 0x00005630458488da n/a (gnome-shell) (Plus many threads in __GI___poll, futex_wait_cancelable, and g_cond_wait_until. Let me know if you need those.) Once, I observed this additional log message after the crash: Sep 06 11:13:15 bolt gnome-shell[6491]: invalid (NULL) pointer instance Sep 06 11:13:15 bolt gnome-shell[6491]: g_signal_emit_by_name: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed This happens even with all extensions disabled. Downgrading to gnome-shell 3.28 (and, correspondingly, downgrading to libmutter-2-0 3.28.3-2 and its gir package) gets rid of the issue. I would be grateful for any hints on what might be wrong. Thanks!
