[g-a-devel]ref counting issue ...

[Michael Meeks <michael ximian com>]

Hi Padraig,

	Looks like a ref counting problem; somehow the accessible seems to have
got destroyed - or not got created yet. Whatever the cause, we need some
NULL checks around here perhaps:

#6  0x40cf6560 in gail_focus_notify (widget=0x8406ab8) at gail.c:352
352	      atk_focus_tracker_notify (atk_obj);
(gdb) l
347	      gail_focus_notify_when_idle (focus_widget);
348	    }
349	  else
350	    {
351	      atk_obj  = gail_get_accessible_for_widget (focus_widget,
&transient);
352	      atk_focus_tracker_notify (atk_obj);
353	      if (transient)
354	        g_object_unref (atk_obj);
355	    }
356	}

	The trace:
