The GTK side has a loop which hides all children then shows them after translation. I don't understand why this doen't show the widgets which aren't wanted (such as the alpha warning). Patch above saves the state of each widget and shows it if it was shown before, this assumes the state is correct at the time of saving which I'm not convinced about (it isn't for alpha_warning so an extra save added in there).

This bug was fixed in the package ubiquity - 2.2.13

---------------
ubiquity (2.2.13) lucid; urgency=low

  [ Evan Dandrea ]
  * In oem-config, support removing packages that were not part of the
    base install and are not needed in the final system by preseeding
    oem-config/remove_extras to true (LP: #315644, LP: #553184).

  [ Roman Shtylman ]
  * Kde_ui:
    - fixed (LP: #550466) (LP: #550472) using kmessage box for quit dialog
    - fixed (LP: #540202) hide widgets until translated
