Thank you Sebastien.
Usual, what schedule time happening upload the GTK+3.0 source package in 
Precise repository?
Will be awailable this fix before 12.04.2 release, or enough shorter 
time and have a scheduled upload this package related already?

  [Precise only] Some keyboard navigation breakage with GTK Notebook

Status in “gtk+3.0” package in Ubuntu:

Status in “gtk+3.0” source package in Precise:

Bug description:
  Dear Developers,

  In Ubuntu 12.04 with GTK notebook containing dialogs some time keyboard navigation is broken if the user using SHIFT+TAB key combination. I copying test case for bug 669986 upstream report, with already fixed I think in GTK+ 3.5.6. The fix is land correct in Ubuntu Quantal too.
  Joanmarie Diggs Orca developer in upstream report wrote following testcase:Steps to reproduce:
  "1. Launch gtk3-demo
  2. Run the 'Printing' demo
  3. Select a printer so that the 'Print' button becomes available
  4. Press Shift+Tab to move from the selected printer to the 'General' notebook
  tab
  5. Press Shift+Tab to move from the 'General' notebook tab to the 'Print'
  button.

  Expected result: Focus would move to the 'Print' button.

  Actual result: Focus skips the action area completely and the 'Reverse'
  checkbox gains focus.
  6. Press Tab from the 'Reverse' checkbox to give focus to the 'Print' button
  7. Press Tab once more to give focus to the 'General' notebook tab
  8. Press Shift+Tab to move from the 'General' notebook tab to the 'Print'
  button.
  This time it works as expected.

  It seems that giving focus to something on a notebook page prior to
  Shift+Tabbing is what causes the action area to be skipped over."

  I searched what commit fixed this issue with upstream level, following commit fixed this issue in GTK+ 3.5.6:
  "From 3056324570dc5f0e94a9da0958e4980199200ab6 Mon Sep 17 00:00:00 2001

  Subject: GtkNotebook: Fix reverse tab order

  When using Shift-Tab to move the focus out of page content onto
  the tab label, we end up in a situation where both Tab and Shift-Tab
  move focus back into the page, which is not really what is expected
  when the notebook is part of a dialog.

  Instead, arrange things so that using Shift-Tab with focus on a
  tab label moves the focus out of the notebook."

  This bug is important with accessibility, if the Ubuntu 12.04 LTS
  release policy prowide possibility to fix this bug, please fix this
  issue.
