Bug description:
  [Impact]

  Formatting a SD card using the disk utility fails with an error
  message

  "Error formatting disk - Error synchronizing after initial wipe: Timed
  out waiting for object (udisks-error-quark, 0)"

  The underlying problem is that the "wipefs" tool from util-linux does
  not work any more.

  You can work around this bug in gnome-disk-utility using these steps:

  * After selecting the SD card, instead of clicking the gear icon to format,
    click the partition in the "Volumes" section.

  * Delete the partition ("minus" icon)

  * Create a new partition

  [Test Case]

  $ sudo modprobe scsi_debug dev_size_mb=200
  # this creates a new /dev/sdX, usually /dev/sdb; check dmesg!

  # now create a partition table
  $ cat <<EOF | sudo sfdisk /dev/sdb
  # partition table of /dev/sdb
  unit: sectors

  /dev/sdb1 : start=       32, size=   409568, Id=83
  /dev/sdb2 : start=        0, size=        0, Id= 0
  /dev/sdb3 : start=        0, size=        0, Id= 0
  /dev/sdb4 : start=        0, size=        0, Id= 0
  EOF

  # now create an ext4 file system:
  $ sudo mkfs.ext4 /dev/sdb1

  # check contents:
  $ sudo blkid -p /dev/sdb /dev/sdb1
  /dev/sdb: PTTYPE="dos"
  /dev/sdb1: UUID="4bd1c542-a61f-43c4-a7e5-cc50e66e6b5a" VERSION="1.0" 
TYPE="ext4" USAGE="filesystem" PART_ENTRY_SCHEME="dos" PART_ENTRY_TYPE="0x83" 
PART_ENTRY_NUMBER="1" PART_ENTRY_OFFSET="32" PART_ENTRY_SIZE="409568" 
PART_ENTRY_DISK="8:16"

  # wipe:
  $ sudo wipefs -a /dev/sdb

  # now check contents again
  $ sudo blkid -p /dev/sdb /dev/sdb1

  # in the broken case, you will still see a "dos" partition table and
  the ext4 partition; in the working case, /dev/sdb won't show anything
  and /dev/sdb1 does not exist any more
