ubiquity on intrepid kubuntu fails to start

Specific to kubuntu; the issue here is that kdesudo-kde4 is not on the CD, so ubiquity isn't able to successfully reexec itself with root permissions under kdesudo.

That alone is probably insufficient to fix this bug, since kdesudo-kde4 doesn't ship kdesudo in /usr/bin, it ships it under /usr/lib/kde4/bin; so ubiquity still won't be able to re-exec itself without some path changes. Opening a kdesudo-kde4 task for this.

This bug was fixed in the package ubiquity - 1.9.1

---------------
ubiquity (1.9.1) intrepid; urgency=low

  [ Evan Dandrea ]
  * Fixed the missing definition of HOSTNAME_BADDOTS, which was causing a
    crash when the user entered a hostname that ended in a dot.
  * Fix a crash introduced by the fix for LP: 40590.

  [ Jonathan Riddell ]
  * ubiquity-frontend-kde depends on kde-window-manager (KDE 4), not kwin
    (KDE 3).

  [ Colin Watson ]
  * Update file name for apt-setup 1:0.32.
  * Add apt-setup local generator to improve preseeding facilities.
  * KDE frontend: Use kdesudo-kde4 for now, and adjust ubiquity-wrapper to
    look for it in /usr/lib/kde4/bin/ (LP: #247537).
  * Automatic update of included source packages (limited to those packages
    where ubiquity code already expects newer versions): apt-setup
    1:0.37ubuntu2, partconf 1.27, partman-auto 78ubuntu1, partman-auto-loop
    0ubuntu15, partman-base 121ubuntu3, partman-basicfilesystems 60ubuntu1,
    partman-basicmethods 39ubuntu1, partman-efi 17ubuntu1, partman-ext3
    52ubuntu1, partman-jfs 26ubuntu1, partman-newworld 19ubuntu1,
    partman-partitioning 59ubuntu2 (LP: #247519), partman-reiserfs
    41ubuntu1, partman-target 55ubuntu1, partman-xfs 41ubuntu1.

kdesudo fails to start ubiquity usefully because xauth generate fails; this turns out to be because the SECURITY extension is missing from the X server.

xorg-server (2:1.4.99.905-0ubuntu4) intrepid; urgency=low

  * debian/rules:
    Add --enable-xcsecurity --enable-appgroup. The SECURITY module was
    disabled by default in commit 86b2e59bfb79bd042a13c35fbb4ccecec576f629,
    as part of the SELinux merge. However, we need the security module
    for xauth on Kubuntu, else ubiquity fails. (Ref. LP 247537)

Now that X has been fixed, the kdesudo path change is not release-critical.

This is fixed by the newer version in kdesudo (as opposed to kdesudo-kde4).
