Warnings about wrong hostnames untranslated in the installer

Same thing happens when checking the validity of the user name.

Still says TODO:

def check_hostname(hostname):
    """Returns a newline separated string of reasons why the hostname is
    invalid."""
    # TODO: i18n
    e = []
    # Ahem. We can cheat here by inserting newlines where needed. Hopefully
    # by the time we translate this, GTK+ will have decent layout management.
    for result in validation.check_hostname(utf8(hostname)):
        if result == validation.HOSTNAME_LENGTH:
            e.append("Must be between 1 and 63 characters long.")
        elif result == validation.HOSTNAME_BADCHAR:
            e.append("May only contain letters, digits,\nhyphens, and dots.")
        elif result == validation.HOSTNAME_BADHYPHEN:
            e.append("May not start or end with a hyphen.")
        elif result == validation.HOSTNAME_BADDOTS:
            e.append('May not start or end with a dot,\n'
                     'or contain the sequence "..".')
    return "\n".join(e)

This bug was fixed in the package ubiquity - 2.9.20

---------------
ubiquity (2.9.20) precise; urgency=low

  [ Colin Watson ]
  * Restore old fallback code in case /cdrom/casper/filesystem.size doesn't
    exist (LP: #557388).
  * Fix some more uses of deprecated python-apt APIs.
  * ubiquity-dm: Try openbox after openbox-lubuntu (LP: #888107).
  * Thomson SA is now called Technicolor SA (LP: #856992).
  * Limit maximum length of username editing widgets to 32 (LP: #831319).
  * UTF-8-encode the syslog message when a geoname lookup fails, since it
    might include non-ASCII characters entered by the user (LP: #928891).
  * Run test suite under xvfb-run by default when running it from the
    command line. 'tests/run --no-xvfb' inhibits this behaviour for cases
    where it's useful to see the UIs constructed by the test suite.
  * Stop manually inserting newlines in hostname and username errors. GTK+
    3 seems to do a reasonable job of wrapping these by itself now.
  * Port the user page from GtkTable to GtkGrid, so that we get sensible
    height-for-width geometry management (LP: #830933).
  * Internationalise hostname and username validation errors (LP: #784825).

  [ Mario Limonciello ]
  * Have two separate failsafe attempts for 'fbdev' and 'vesa'. It's
    possible that /dev/fb0 will exist but be backed by a VGA framebuffer
    causing X to exit non-zero.

  [ Stéphane Graber ]
  * Use the Xubuntu wallpaper when available. (LP: #936572)
  * Detect bogus DNS servers and ignore them. (LP: #760884)
  * Automatic update of included source packages: base-installer
    1.122ubuntu5, choose-mirror 2.39ubuntu4.
