This crash looks to be due to an infinite loop between a child and parent in atk.
This is what I think is happening: - The loops begins with a call to atk_component_get_extents() on a gtk notebook page. - atk_component_get_extents() then calls iface->get_extents() [1] - which translates to gtk_notebook_page_accessible_get_extents() [2] - the gtk notebook page then calls atk_component_get_extents() on it's child [3] - where the child's iface->get_extents() translates to atk_socket_component_real_get_extents() [4] - in which the child calls atk_component_get_extents() again on its parent [5] - - - - [1] https://gitlab.gnome.org/GNOME/atk/-/blob/9118d44778e4d3a05810012cdcaa69eb4db2c389/atk/atkcomponent.c#L299 [2] https://gitlab.gnome.org/GNOME/gtk/-/blob/4ff578db10fe01de662e478ffd5f9ff205e89074/gtk/a11y/gtknotebookpageaccessible.c#L342 [3] https://gitlab.gnome.org/GNOME/gtk/-/blob/4ff578db10fe01de662e478ffd5f9ff205e89074/gtk/a11y/gtknotebookpageaccessible.c#L325 [4] https://gitlab.gnome.org/GNOME/atk/-/blob/e7276a0c47a0bd3cfb5654583ca3358ddf51a609/atk/atksocket.c#L104 [5] https://gitlab.gnome.org/GNOME/atk/-/blob/e7276a0c47a0bd3cfb5654583ca3358ddf51a609/atk/atksocket.c#L198 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870508 Title: ubiquity crashed with SIGSEGV in g_type_check_instance_is_a() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/atk1.0/+bug/1870508/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
