accerciser crashed with TypeError in __call__(): 'TreePath' object does not support indexing

I'm checking A11Y of Unity2D.

The A11Y framework used is a bit hairy - much is a backport from Qt4.8, and using older qt-atspi.

Also getting these errors:
process 27034: arguments to dbus_message_new_method_call() were incorrect, assertion "destination == NULL || _dbus_check_is_valid_bus_name (destination)" failed in file ../../dbus/dbus-message.c line 1203.
This is normally a bug in some application using the D-Bus library.
