Re: Bug, probably related to Custom Themes.

[Richard M. Stallman]

    I think that Customize should only write to .emacs when the user
    clicks on the "Save" button.  Maybe "Erase Customizations" should only
    reset the values in the Customize buffer, but not make them take
    effect.

I am not sure in principle; anyway, now is not the time to consider
changing that.

However, the issue at hand seems to be a different one:
WHICH value it should install.  Isn't that so?
