add_keybindings() kept the GActionEntry around but not the 'name' string of these. Those were freed by with overview_bindings and app_view_bindings. When PhoshHome gets destroyed we iterated over self->actions referencing already freed string names. To avoid this don't track GActionEntries but rather just the action names which also avoids reconstructing the GActionEntry in PhoshGnomeShell:remove_action_entries(). This avoids the following valgrind error: ==14994== Invalid read of size 1 ==14994== at 0x56623D0: g_str_hash (ghash.c:2335) ==14994== by 0x5660D6A: g_hash_table_lookup_node (ghash.c:473) ==14994== by 0x5660D6A: g_hash_table_lookup (ghash.c:1513) ==14994== by 0x54CDCBB: g_simple_action_group_remove_action (gsimpleactiongroup.c:234) ==14994== by 0x17F480: phosh_shell_remove_global_keyboard_action_entries (shell.c:1287) ==14994== by 0x168E2E: phosh_home_dispose (home.c:349) ==14994== by 0x55E2438: g_object_run_dispose (gobject.c:1226) ==14994== by 0x17CA10: panels_dispose (shell.c:271) ==14994== by 0x17CA10: phosh_shell_dispose (shell.c:346) ==14994== by 0x55E10A2: g_object_unref (gobject.c:3465) ==14994== by 0x55E10A2: g_object_unref (gobject.c:3395) ==14994== by 0x12B197: glib_autoptr_clear_GObject (gobject-autocleanups.h:27) ==14994== by 0x12B197: glib_autoptr_clear_PhoshShell (shell.h:57) ==14994== by 0x12B197: glib_autoptr_cleanup_PhoshShell (shell.h:57) ==14994== by 0x12B197: main (main.c:80) ==14994== Address 0xde089f0 is 80 bytes inside a block of size 96 in arena "client" This was spotted on a regular phosh shutdown but would also trigger when moving the primary display which recreates PhoshHome.
