Can't open Orca settings on Ubuntu 13.04

I use Ubuntu 13.04. I found out Orca could be enabled in Universal Access, but I cannot find its GUI based settings manager.

I can't even start its settings manager via the command orca --setup or with the key combination Insert+Space.

It's very convenient/needed for a blind user to change the general settings like speaking rate, pitch and many other things. It's a lot less accessible if one has to run orca --text-setup every time or edit a configuration file.

How can I open the Orca settings manager?

The orca setup is now working in 16.04 (LTS)

Please upgrade to the latest version of Ubuntu.
