Advanced Options can not be OK'ed

I think it is just not happy with my choice of boot device. It is on a raid. If I choose one of the raw devices (or their "partitions" which ideally should not appear), the OK is clickable.

But now that I got rid of the raw devices, and only see the raid devices, none of the choices qualify, and even if I untick the boot loader check-box, I can not click OK. So I am not able to install without having the installer trying to install grub (see bug 344291).

This bug was fixed in the package ubiquity - 1.12.0

ubiquity (1.12.0) jaunty; urgency=low

  [ Colin Watson ]
  * Update for new message context system in GTK+ 2.15.1, and update
    imported translations from gtk+2.0 2.16.0-1ubuntu2.
  * Stop setting message attribute in InstallStepError; it isn't used and it
    generates a deprecation warning with Python 2.6. Similarly, rename
    PartedServerError's message attribute to parted_error.
  * Always set auto-login for OEM installations.
  * KDE frontend:
    - Hide auto-login and require-password radio buttons for OEM
      installations.
  * Remove reimplementation of gdm and kdm auto-login support for OEM
    installations, since user-setup handles this now and the duplication
    causes oem-config to be unable to undo autologin (LP: #347900).
  * Fix ubiquity/install_bootloader handling (LP: #348660):
    - Check the seen flag rather its value when deciding whether to override
      it with the UI's value.
    - Outside automatic mode, default the UI's "Install boot loader"
      question to the value of ubiquity/install_bootloader.
  * Offer "Yes" and "No" choices for user-setup/password-weak (LP: #349173).
  * Depend on grub | grub-pc, and don't remove grub-pc until after
    grub-installer has had the chance to decide whether it wants to use it
    (LP: #349835).
  * Add a compatibility wrapper for update-dev to ensure that it never
    attempts to call 'udevadm trigger', which isn't necessary in ubiquity
    and can cause problems (LP: #349937).
  * Permit dmraid-style /dev/mapper/* device names in advanced boot loader
    selector, as well as disk and partition numbers over 9 (LP: #342354).
  * Remove /target/var/lib/apt-xapian-index per Michael Vogt, since it needs
    to be rebuilt based on the installed system's sources.list, and apt's
    cron.daily script and/or synaptic will do this.
  * Preserve ordering of automatic partitioning choices when replacing them
    with our customised strings (LP: #351547).
  * Update translations from Launchpad.
  * Automatic update of included source packages: apt-setup 1:0.37ubuntu11,
    base-installer 1.98ubuntu4, console-setup 1.28ubuntu7, grub-installer
    1.36ubuntu5, hw-detect 1.71ubuntu6, partman-base 129ubuntu4,
    partman-target 58ubuntu6.

  [ Evan Dandrea ]
  * Make the partman/unmount_active dialog a yes or no question
    (LP: #346589).
  * Sort the list of regions on the timezone page (LP: #344334).
  * Merge Roman's city placement code into the GTK frontend.
  * Work in bytes rather than percentages in the partition bar code
    (LP: #336203).
  * Fix partition bar slider (for resizing) code by adding correct
    calculations for bounds checking and slider positioning.
  * Properly encode data from os-prober (LP: #345573).
  * Make sure that the before and after partitioning bars use the same
    colors for the same partitions (LP: #289324).
  * Fix the placement of the partition bars in scrolled windows when
    necessary.
  * Don't let the partition bars eat up any extra space.
  * Move selecting a disk from radio buttons to a drop down box on the
    automatic partitioning page. This saves a lot of space when...
