repeated/looped asking of same question

Binary package hint: debian-installer

i'm trying to preseed the netinstallation of ubuntu lucid lynx 10.04 and it keeps asking me the same thing:

Partition disks

No file system is specified for partition #1 of LVM VG vg0, LV dummy.

I can say Yes or No, it loops here.

Here's the partman preseed details:
