Bug description:
  The problem is with is_disk_used in cc_disk_setup.py

  use_count is an array, which doesn't have a splitlines attribute.
  This is broken on ubuntu precise 12.04 with the latest updates.

  def is_disk_used(device):
      """
      Check if the device is currently used. Returns true if the device
      has either a file system or a partition entry
      is no filesystem found on the disk.
      """

      # If the child count is higher 1, then there are child nodes
      # such as partition or device mapper nodes
      use_count = [x for x in enumerate_disk(device)]
      if len(use_count.splitlines()) > 1:
          return True

      # If we see a file system, then its used
      _, check_fstype, _ = check_fs(device)
      if check_fstype:
          return True

      return False
