Bug#625517: os-prober: ubuntu partition found on Debian install, but then lost upon kenel update

[Paul Johnson <pauljohn32@gmail.com>]

Package: os-prober
Version: 1.42
Severity: normal
Tags: d-i


When I installed Debian 6.0.1 squeeze, the Ubuntu partition
was found and put into grub menu.  Later I installed some
packages from "testing" and after that the Ubuntu partition
was not found when the kernel upgraded.

I can still manually put the Ubuntu into the grub.cfg file to start it

 menuentry 'Ubuntu, with Linux 2.6.38-8-generic' --class ubuntu
--class gnu-linux --class gnu --class os {
        recordfail
        set gfxpayload=$linux_gfx_mode
        insmod part_msdos
        insmod ext2
        set root='(/dev/sda,msdos3)'
        search --no-floppy --fs-uuid --set=root
2eb8cda6-366c-4ef7-b7da-8ff292ca7e61
        linux   /vmlinuz-2.6.38-8-generic
root=UUID=18c56003-c1d4-4fa1-8753-a20bf3034b7e ro   quiet splash
vt.handoff=7
        initrd  /initrd.img-2.6.38-8-generic
 }


however, os-prober still does not see Ubuntu, but it does see Windoze:

$ sudo os-prober

/dev/sda1:Microsoft Windows XP Professional:Windows:chain

My Ubuntu is installed with a boot partition /dev/sda3 and the main root is /dev/sda7.
