7.10 Install turned Windows partition into swap space!

A graduate student I've been working with installed Ubuntu 7.10 on a
machine today. He used the guided setup to create a 50/50 XP/Ubuntu dual
boot system.

Upon rebooting, we found that the windows partition was gone. After
inspecting the partition table with fdisk, we found that /dev/sda2 (the
original windows partition) had been turned into swap space. 

I tried manually switching the partition type to ntfs and mounting, but
it had apparently been overwritten by mkswap.

I checked the installer logs for parted and saw that for most of the
install process, the partitioner was treating the windows partition as
an NTFS partition, then at some point it decided to switch it to swap.

What's more odd is that (huge) swap space isn't even being used by
Ubuntu. It doesn't appear in fstab, nor is it swapon'ed any other way.

Has anyone seen something like this before? I certainly haven't, but
it's a bit frightening.

I'm helping out at an Ubuntu InstallFest this weekend and would hate to
be the cause of severe data loss.
