Bug#213905: No own logos with xdm: xdm error: Unable to stat() pixmap file

[Matthias Dehn <p18y008@public.uni-hamburg.de>]

Package: xdm
Version: 4.1.0-16

It is not possible to chose an own logo for the login screen via xdm in
/etc/X11/xdm/Xresources. The login widget shows the text only. The
delivered logos  (debian.xpm, debianbw.xpm, XFree86.xpm, XFree86bw.xpm)
can be used without any problems.

One may (hopefully) reproduce the error the following way:

* In /etc/X11/xdm/pixpaps:

/etc/X11/xdm/pixmaps# cp debian.xpm test.xpm
/etc/X11/xdm/pixmaps# ls -l
        (...)
-rw-r--r--    1 root     root        54701 16. Apr 2002  debian.xpm
-rw-r--r--    1 root     root        54701  3. Okt 12:05 test.xpm
        (...)

* Changing /usr/X11R6/lib/X11/xdm/Xresources:

        (...)
#if PLANES >= 8
  xlogin*logoFileName: /etc/X11/xdm/pixmaps/test.xpm
! xlogin*LogoFileName: /etc/X11/xdm/pixmaps/debian.xpm
#else
        (...)

* Restarting X

* In /var/log/xdm.log:
xdm error (pid 961): Unable to stat() pixmap file
/etc/X11/xdm/pixmaps/test.xpm

* A small C-program shows no difference of stat()-return values, of
course:
---snip--: test.c :---
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <stdio.h>

const char test[]   = "/etc/X11/xdm/pixmaps/test.xpm";
const char debian[] = "/etc/X11/xdm/pixmaps/debian.xpm";

int main()
{
  struct stat* buf;
  printf("stat(\"%s\", buf) = %d \n",
         test, stat(test,buf));
  printf("stat(\"%s\", buf) = %d \n",
         debian, stat(debian,buf));

  return 0;
}
---snap---

* It returns:

# ./test
stat("/etc/X11/xdm/pixmaps/test.xpm", buf) = 0
stat("/etc/X11/xdm/pixmaps/debian.xpm", buf) = 0

* I'm using Debian GNU/Linux 2.4, Kernel 2.4.18-bf2.4, libc 2.2.5

Thanks a lot for any useful hint.

        Cheers,
                Matthias
