I just tried it out myself. Installed karmic alpha 3 with GPT,
seperate /boot and / on LVM

root@ubuntu:~# grub-probe -t abstraction /
lvm
root@ubuntu:~# grub-probe -t partmap /
gpt
root@ubuntu:~# grub-probe -t fs /
ext2

Maybe your LVM has an unknown metadata header or multiple data/metadata
areas.
I think in these cases the error isn't always shown or something has
changed that they aren't anymore displayed.
Multiple metadata areas are now fixed upstream.
