I had exactly the same behavour with 14.04 if any pre-existing raids were present.
Installer fails with: "partman-auto-raid: Error: incorrect directory for /dev/mdXXX"
I can only confirm that wiping disks with dd gets you passed this, however, using mdadm to zero the superblock instead may just work, I have not tested this.
