Bug#604845: grub-pc: update-grub fails with "error: Couldn't find PV pv1. Check your device.map."

Package: grub-pc
Version: 1.98+20100804-8
Severity: important

Update-grub uses grub-probe to get more information on "/usr/share/grub/unicode.pf2". 
This fails and as a result /boot/grub/grub.cfg is not created.

Workaround: add in /etc/default/grub
GRUB_FONT=/boot/grub/unicode.pf2



# update-grub
/usr/sbin/grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).

/usr/sbin/grub-probe: error: Couldn't find PV pv1. Check your device.map.


In /etc/grub.d/00_header the following line fails:
 prepare_grub_to_access_device `${grub_probe} --target=device "${GRUB_FONT_PATH}"`

# grub-probe --target=device "/usr/share/grub/unicode.pf2"
grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).
grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).
/dev/mapper/main-usr

Which is correct.

Looking at /usr/lib/grub/grub-mkconfig_lib the function "prepare_grub_to_access_device ()"
has the following grub-probe commands:
  abstraction="`${grub_probe} --device ${device} --target=abstraction`"
  partmap="`${grub_probe} --device ${device} --target=partmap`"
  fs="`${grub_probe} --device ${device} --target=fs`"
  fs_uuid="`${grub_probe} --device ${device} --target=fs_uuid 2> /dev/null`"

with device=/dev/mapper/main-usr

grub-probe fails for target=abstraction and target=partmap:
# grub-probe --device /dev/mapper/main-usr --target=abstraction
grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).
grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).
grub-probe: error: Couldn't find PV pv1. Check your device.map.

# grub-probe --device /dev/mapper/main-usr --target=partmap
grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).
grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).
grub-probe: error: Couldn't find PV pv1. Check your device.map.

grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).
ext2

# grub-probe --device /dev/mapper/main-usr --target=fs_uuid
grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).
grub-probe: warn: Discarding improperly nested partition (hd3,msdos3,msdos1).

And with this error update-grub aborts.
