Public bug reported:

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
