ubiquity fails to start in kubuntu

This bug was fixed in the package ubiquity - 2.1.5

---------------
ubiquity (2.1.5) lucid; urgency=low

  [ Mario Limonciello ]
  * Mythbuntu: Don't start MySQL using the upstart scripts since they don't
    work in a chroot. (LP: #494830)

  [ Colin Watson ]
  * Update two more edit_partition calls to account for renamed format ->
    fmt argument (LP: #494608).
  * Remove hack forcing the use of sudo with the KDE frontend, as it no
    longer appears to be necessary and things break if we don't use kdesudo
    (LP: #494997).
  * Make ubiquity.parted_server's logging to /var/log/partman more
    distinctive.
  * Set sensible permissions on /var/log/installer/debug, not os.open's
    default of 0755.
  * Gather basic information from parted_server using the PARTITIONS command
    (all partitions on a disk at once), which is slightly faster than
    PARTITION_INFO (one partition at a time).
  * Initialise automation_error_cmd, error_cmd, and success_cmd to '' rather
    than None, since that's what's checked by the functions that use them.
  * Unlink /var/lib/localechooser/langlevel even if unlinking
    /var/lib/localechooser/preseeded fails.
  * Regain privileges to unlink /var/lib/localechooser/preseeded and
    /var/lib/localechooser/langlevel.
  * Enable debconffilter debugging if UBIQUITY_DEBUG_CORE=1, so that we can
    set DEBCONF_DEBUG=developer rather than DEBCONF_DEBUG=developer|filter
    which cdebconf doesn't understand.
  * Automatic update of included source packages: console-setup 1.34ubuntu5,
    partman-base 135ubuntu2.
