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

[Tim Smith <timsmith3@gmail.com>]

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.

Mmm, it doesn't match the binaries on my system, it looks like you have
a mixture of packages from stable, testing and unstable...

Could you for a start upgrade these packages:

  python3-pyatspi libatspi2.0-0

and enable this in apt's sources.list:

  deb http://debug.mirrors.debian.org/debian-debug/ stable-debug main
  deb http://debug.mirrors.debian.org/debian-debug/ testing-debug main
  deb http://debug.mirrors.debian.org/debian-debug/ unstable-debug main

and install these packages:

  gdb python3-dbg python3-pyatspi-dbgsym libatspi2.0-0-dbgsym libdbus-1-3-dbgsym libglib2.0-0-dbgsym

and run gdb yourself on the core file:

  gdb /usr/bin/python3 core

and at the gdb> prompt, type

  bt full

and send us the result.
