Bug#872299: gnome-orca: Orca segfaults on startup

[Tim Smith]

I upgraded python3-pyatspi and libatspi2.0-0, and now orca runs!  Let me
know if you still want me to install the debug packages and send you the
gdb result using the old core file.

Unfortunately, there is a new problem: there is no audio.  The console
output shows several errors:

/usr/lib/python3/dist-packages/pyatspi/Accessibility.py:184: Warning:
g_object_unref: assertion 'G_IS_OBJECT (object)' failed
  Atspi.Event.host_application = property(fget=lambda x:
x.source.get_application())

(orca:8089): Gtk-CRITICAL **: gtk_notebook_get_tab_label: assertion 'list
!= NULL' failed

/usr/lib/python3/dist-packages/pyatspi/Accessibility.py:41: Warning:
g_object_unref: assertion 'G_IS_OBJECT (object)' failed
  len=self.get_child_count()

Thanks for any help you can give.

Tim
