I can't find any other reports of this crash yet. You do seem to have a few extensions installed:
b'org.gnome.shell' b'enabled-extensions' b"['places-menu@gnome-shell- extensions.gcampax.github.com', 'clipboard-indica...@tudmotu.com', 'onboard_indica...@onboard.org', 'straighttop...@peclu.net.net', 'gsconn...@andyholmes.github.io', 'user-theme@gnome-shell- extensions.gcampax.github.com', 'drive-menu@gnome-shell- extensions.gcampax.github.com', 'always-show-workspa...@system76.com', 'extendedgestu...@mpiannucci.github.com', 'slideforkeybo...@simon.schumann.web.de']" Please try removing all of them and see if that fixes the problem. If so then we would need to find out which extension it is. ** Summary changed: - gnome-shell crashed with SIGSEGV in shell_app_dispose() + gnome-shell crashed with SIGSEGV in shell_app_dispose() from g_object_unref() from g_hash_table_remove_node() from g_hash_table_remove_internal() from _shell_app_system_notify_app_state_changed() from shell_app_state_transition() from _shell_app_remove_window() ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete ** Information type changed from Private to Public -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789933 Title: gnome-shell crashed with SIGSEGV in shell_app_dispose() from g_object_unref() from g_hash_table_remove_node() from g_hash_table_remove_internal() from _shell_app_system_notify_app_state_changed() from shell_app_state_transition() from _shell_app_remove_window() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1789933/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
