Description Jonathan Briggs 2011-08-22 20:21:44 UTC 
I ran Orca some time last week and it turned on accessibilty in Gnome 3.

Today when I switch to the Evolution calendar view, it crashed with a seg fault.

Debugging shows this backtrace:

+ Trace 228168

  • #0 et_get_n_children
    at gal-a11y-e-table.c line 132
  • #1 ??
    from /usr/lib64/gtk-3.0/modules/libatk-bridge.so
  • #2 g_main_context_dispatch
    from /lib64/libglib-2.0.so.0
  • #3 ??
    from /lib64/libglib-2.0.so.0
  • #4 g_main_loop_run
    from /lib64/libglib-2.0.so.0
  • #5 gtk_main
    from /usr/lib64/libgtk-3.so.0
  • #6 main
    at main.c line 734 

The crash code is:
    et = E_TABLE (gtk_accessible_get_widget (GTK_ACCESSIBLE (a11y)));                 │
   
--> if (et->group) {                                           

The variable 'et' is optimized out but the disassembly is:
    mov    0x50(%rax),%rbx 

And register rax is 0. So 'et' must have been NULL.

The contents of 'a11y' do not look that useful but they are:
{object = {parent = {parent = {g_type_instance = {g_class = 0xc83bb0}, ref_count = 3, 
        qdata = 0x0}, description = 0x0, name = 0xc70fa0 "Memos", accessible_parent = 0x0, 
      role = ATK_ROLE_UNKNOWN, relation_set = 0xcbb560,	layer = ATK_LAYER_INVALID}, priv = 0xccb720}}

If I turn off org.gnome.desktop.interface toolkit-accessibility using dconf-editor, then run Evolution again, it does not crash.
