This bug was fixed in the package ubiquity - 2.9.30

---------------
ubiquity (2.9.30) precise; urgency=low

  [ Adam Conrad ]
  * Drop gui/qt/images/squares.png and replace it with a single pixel
    transparent PNG as a placeholder for future changes (LP: #942543)

  [ Evan Dandrea ]
  * Lazily unmount partitions in the check for a Windows partition to
    install Wubi on when we have a full partition table (LP: #956531).
  * Add a small program for testing the Gstreamer webcam code.
  * Fix broken test video output in the GI webcam module.

  [ Stéphane Graber ]
  * set_indicator_keymaps() doesn't actually receive a full locale but
    instead just the language code. That means that the code trying to
    guess a layout based on the default country won't work.
    Drop all of that code and replace by a static map to override the
    default keyboard layout/variant for a language. (LP: #956912)
  * Merge and update Alessio Treglia's branch to make the slideshow
    optional depending on (ubiquity/hide_slideshow) (LP: #690912)
  * Also call setxkbmap directly from set_indicator_keymaps() to ensure
    we actually switch to the first layout in the list. (LP: #956912)
  * Properly mark the KeyboardQuery dialog as a child of ubiquity.
    (LP: #955265)

  [ Martin Pitt ]
  * tests/test_migrationassistant.py: Fix to work with pygobject 3.1.92.

  [ Barry Warsaw ]
  * When Try Ubuntu has been clicked once, don't respond to subsequent
    clicks. (LP: #911907)
