"debian-40r1-i386-xfce-CD-1.iso" --not bootable

[Manning <tendoku@peak.org>]

I have found "debian-40r1-i386-xfce-CD-1.iso" at:
http://cdimage.debian.org/debian-cd/4.0_r1/i386/iso-cd/
to be unbootable on a tested machine.

bobo@foo2:~/Debian$ cat MD5SUMS.txt |grep xfce
feab037058e6c612e3f367ae981188d9  debian-40r1-i386-xfce-CD-1.iso
bobo@foo2:~/Debian$ md5sum debian-40r1-i386-xfce-CD-1.iso
feab037058e6c612e3f367ae981188d9  debian-40r1-i386-xfce-CD-1.iso

Maybe a problem with the master?
