Karmic Amd64, same problem, no su-to-root

[Roosje]

I am running Ubuntu 9.10 (Karmic Koala) and am trying to run "Back in Time (root)" from the Applications menu. Initially it wouldn't start at all, I modified the command from "su-to-root -X" to "gksudo -S" hoping that it would solve the problem. Now I get a window at the bottom stating that "Back in Time (root) is starting" but then it disappears and nothing happens.

Is this a known issue and is there anything that I can do to try and fix this?

FYI: The su-to-root version gives me this message:
Failed to execute child process "su-to-root" (No such file or directory)

Thanks,
Steve

This is essentially the same bug as 466088, i.e. the su-to-root command is not available.
