    This patch solved the problem! Thanks!


    On a different matter;

    While playing around with 2.5.40 a bit I noticed something really weird:
    I use the ZSH shell and my prompt basically ends with the %# code which is
    supposed to show a '%' if you're not root and '#' if you are root.
    In 2.5.40, zsh shows # unconditionally. (In 2.4.19pre1 which I normally run,
    it works as expected). Really weird..
