Hah! I found out why this doesn't happen for everyone. If I toggle the screen reader on & off again (System Settings->Universal Access->Screen Reader), it stops crashing. If I enable the screenreader again, it starts crashing again.
GNOME _used_ to have a global "enable accessibility" checkbox. It looks like that's been removed & is now handled automatically. If you're not using any individual accessibility option, the global setting is disabled for you. (For efficiency reasons). But the old value of the global "enable accessibility" setting was preserved from before I upgraded. The reason it only happens when GNOME is started normally, is because other environments don't set up accessibility. > #16 0x00007f15a95a6805 in atk_object_real_ref_state_set (accessible=0xce33c0) at atkobject.c:1399 (accessible=0xce33c0) at atkobject.c:1399 (from Stacktrace.txt) ** Summary changed: - synaptic crashes immediately on startup with SIGABRT in raise() [GNOME only?] + synaptic crashes immediately on startup with SIGABRT in raise() [Only when accessibility is enabled, e.g. screen reader] ** Tags added: a11y -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/839219 Title: synaptic crashes immediately on startup with SIGABRT in raise() [Only when accessibility is enabled, e.g. screen reader] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/synaptic/+bug/839219/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
