Comment 4 for bug 160669

When I rename the file to ~/.xscreensaver.old and run xscreensaver-demo, "Langton's Ant" disappears and I have to insert the above line back into the file.
(and yes, I have all xscreensaver packages installed, so that's not the problem. I do also wonder just which other savers aren't listed, though that would be for another bug and another time)

I do know that this has been/is a problem for the following versions of (X)Ubuntu: Dapper Drake (version 4.23-4ubuntu8.1), Feisty Fawn (version 4.24-5ubuntu2.1) and Gutsy Gibbon (version 4.24-5ubuntu3).
(I don't know about Edgy Eft as I skipped that one on my upgrade route)

On Feisty Fawn on a fresh account running Gnome & Gnome's screensaver tool, Langton's Ant doesn't even show up in the list and I'm not sure where to add it.

As I prefer more control over the savers used, I will be using the xscreensaver package, despite the fact that it has been depreciated in Gutsy.
As a result, any update to the gnome-screensaver package that doesn't affect any of the xscreensaver* packages won't help my problem.
(also, I filed this bug against xscreensaver, NOT gnome-screensaver. Sorry to be emphatic, but I really don't like Gnome's over-simplified version and will be avoiding it as much as possible)
