Meanwhile I upgraded Kubuntu to the released version of "jaunty" and
cannot reproduce the problem I originally reported there. Thus I
unfortunately do not know whether your changes fix the problem. Thank
you nevertheless for looking into it - I hope they fix the issue for

at all with Emacs CVS, since the server immediately crashes with:
