This bug was fixed in the package cryptsetup - 2:1.0.6-6ubuntu1

---------------
cryptsetup (2:1.0.6-6ubuntu1) intrepid; urgency=low

  * drop almost all ubuntu specific changes from the cryptsetup package,
    because they have been merged in debian. Thanks a lot!
  * merge from debian, remaining changes:
    - remove versioned build-depency on libdevmapper-dev, we are using a
      rather sophisticated loop for making sure the root filesystem appears.
  * debian/rules: fix location of ltmain.sh
  * don't exit usplash anymore in the init script. LP: #110970, #139363
  * Disable error message 'failed to setup lvm device'. It is harmless, and
    caused by the fact that the udev rules provided by lvm2 are setting up
    the lvm on their own. In debian the scripts here are responsible for this
    but obviously fail in ubuntu. LP: #151532

cryptsetup (2:1.0.6-6) unstable; urgency=high

  * Don't cat keyfile into pipe for do_noluks(). cryptsetup handles
    --key-file=- different for luks and plain dm-crypt mappings. This time
    really (closes: #493848). Thus again upload with urgency=high.

cryptsetup (2:1.0.6-5) unstable; urgency=high

  * Fix watch file to not report -pre and -rc releases as superior.
  * Remove the global var $SIZE from cryptdisks.functions again but keep the
    extended value checks.
  * Remove the udev rules file also in preinst, code taken from example at
    http://wiki.debian.org/DpkgConffileHandling. Thanks Marco d'Itri.
    (closes: #493151)
  * Remove duplicated configuration of --key-file in $PARAMS at do_noluks().
    (closes: #493848).
  * Invoke mount_fs() and umount_fs() in cryptdisks_start, add
    log_action_begin_msg() and log_action_end_msg() to both cryptdisk_start
    and cryptdisks_stop.
  * Copy fd 3 code from do_start and do_stop to cryptdisks_start and
    cryptdisks_stop  to fix "keyscript | cryptsetup". (closes: #493622)
  * This upload fixes two RC bugs, thus upload with severity=high.

cryptsetup (2:1.0.6-4) unstable; urgency=medium

  [ David Härdeman ]
  * Make sure $IGNORE is reset as necessary, patch by Thomas Luzat
    <email address hidden> (closes: #490199)
  * Use askpass in init scripts as well (closes: #489033, #477203)

  [ Jonas Meurer ]
  * Don't copy_exec libgcc1 in cryptopensc initramfs hook, as it's already
    copied by copy_exec /usr/sbin/pcscd automaticly. Thanks to Evgeni Golov
    <email address hidden>. (closes: #490300)
  * Remove the udev rules file again as the relevant rules are now provided
    by dmsetup package which cryptsetup depends on.
  * Add splashy support to askpass, thanks to John Hughes <email address hidden>
    for the patch. (closes: #492451) The support is limited to cryptroot
    though, as splashy freezes for passphrase input dialogs from initscripts.
    Document that in README.Debian.
  * Now that askpass is used as keyscript for interactive mode, it's not
    necessary to set cryptsetup parameter '--tries=$TRIES' and TRIES=1 for
    interactive mode anymore in cryptdisks.functions.
  * Implement special treatment for random passphrases now that we use
    "--key-file=-" for all situations. Only necessary in do_noluks.
  * Fix the passphrase prompt string in initramfs/cryptroot.script to use
    $cryptsource instead of $cryptsources.
  * Major documentation cleanup for lenny:
    - Rewrite CryptoSwap.HowTo in README.Debian, remove CryptoSwap.HowTo.
    - Refer to README.initramfs instead of CryptoRoot.HowTo for encrypted root
      filesystem in README.Debian.
    - Remove outdated docs CryptoRoot.HowTo, usbcrypto.udev and gen-old-ssl-key
      as well as the decrypt_old_ssl keyscript.
    - Remove debian/TODO, didn't have any useful content anyway.
    - Fix section ''9. The "decrypt_derived" keyscript'': Add swap option to
      the example line for crypttab and other minor fixes. Thanks to
      Helmut Grohne <email address hidden>. (closes: #491867)
  * urgency=medium since important (#492451) and security (#477203) bugs get
    fixed by this upload.

cryptsetup (2:1.0.6-3) unstable; urgency=low

  [ Jonas Meurer ]
  * Fix cryptdisks.functions to actually recognize the noauto option. Thanks
    to Christian Pernegger <email address hidden> (closes: #483882)
  * Update patches/02_manpage.patch to fix two more typos, thanks to Bruno
    Barrera Yever <email address hidden> (closes: #476624) and to remove a
    duplicate sentence.
  * Rephrase "Enter password for $crypttarget" to "Enter password to unlock
    the disk $cryptsource ($crypttarget)" in initramfs/cryptroot.script.
  * Bump Standards-Version to 3.8.0:
    - Add a README.source which references /usr/share/doc/quilt/README.source.
    - Add support for debian build option parallel=n to debian/rules.
  * Add a udev rules file to ignore temporary-cryptsetup-* devices, as
    suggested in bug #467200. Thanks to Sam Morris <email address hidden>.
  * Transform debian/copyright into machine-readable code as proposed in
    http://wiki.debian.org/Proposals/CopyrightFormat. Update and add several
    copyright notices.
  * Change reference to docbook xml v4.2 driver file from an online version
    to a local one in the manpage files, as the build process should not
    depend on internet access. Add docbook-xml to build-depends. Thanks to
    Lucas Nussbaum <email address hidden>. (closes: #487056)

  [ David Härdeman ]
  * Hopefully fix askpass to properly handle console and usplash input
    (closes: #477203)
  * Clarify crypttab manpage (closes: #487246)
  * Make regex work if keyfile has extended attributes,
    https://launchpad.net/bugs/231339 (closes: #488131)
  * Support comments in options part of crypttab (closes: #488128)
