There were two ext4 fs bugs that surfaced recently, and they both affected building of live cds. One is rhbz #566905, which was fixed in e2fsprogs-1.41.9-7 (now in F12 stable), and one is rhbz #566329, which was fixed in kernel-2.6.31.12-174.2.22.fc12 (also now in F12 stable). I think it's #566329 that you're seeing, but either way, you want to update both e2fsprogs and the kernel. If you have been running at all with the previous kernel, 174.2.19, you probably have some (fixable) corruption on your root filesystem too, so you should update the kernel, touch /forcefsck, reboot. After all of that, it should build fine.
