This bug was fixed in the package ubuntu-ui-toolkit -
1.3.2060+16.10.20160814

---------------
ubuntu-ui-toolkit (1.3.2060+16.10.20160814) yakkety; urgency=medium

  [ Zoltan Balogh ]
  * Fix OptionSelectorTestCase tests.
  * Fix more OptionSelector autopilot tests

  [ Timo Jyrinki ]
  * Disable documentation building for GLES builds. Fixes LP: #1606222.
  * Replace abs with qFabs due to GCC6 breakage. Fixes LP: #1610943.
  * Limit s390x dependencies more due to upstart/s390x problems and removed
    packages in archives. Fixes LP: #1610951

  [ Andrea Bernabei ]
  * ListItemLayout doc: add elide mode change example and add section about
    labels default properties values. Fixes LP: #1603450.
  * ListItemLayout doc: add explicit note about the need to bind ListItem's
    height to layout's height.
  * More Scrollbar optimizations: 20% faster creation time. Fixes LP: #1606451
  * Scrollbar: fix wrong thumb color on tap/mouse release and increase coverage
    of hover states unit tests. Fixes LP: #1608897

  [ Zsombor Egri ]
  * Fix null pointer property initializer used with 1.3 PageWrapper.
    Fixes LP: #1604780.
  * Fix BottomEdge content URL preloading. Fixes LP: #1604509.

  [Albert Astals Cid ]
  * UCUnits::resolveResource: Prefer image path if it exists. This saves
    searching the disk for @gu images, which is a big speedup. According to
    callgrind loading 100 images from a folder that contains 380 images goes
    from around 3 million instructions per UCUnits::resolveResource call down
    to around 10 thousand. This optimization is ok since it is not correct to
    ship both image.png and image@xxxxxx. You either have to ship gu-enabled
    files or not, but mixing them is not allowed. Searched for cases in which
    that may be happening in my phone and found none. Fixes LP: #1604029.

  [ Tim Peeters ]
  * Configure colors of the buttons in the ActionBar and PageHeader through
    their Styles. Fixes LP: #1597774.
  * Fix assigning of constant values to a grouped property in StyleHints.
    Fixes LP: #1602836.
  * Fix list view keyboard navigation for RightToLeft and BottomToTop
    directions. Fixes LP: #1605634
  * Use external QML files instead of embedded QML strings for autopilot tests.
    Fixes LP: #1578319
  * Fix failing autopilot header tests.
  * Fix ActionSelectionPopover Autopilot CPO tests.

  [Christian Dywan ]
  * Include indexes in "offline" docs and filter out link errors.
    Fixes LP: #1603937.
  * Increase focus ring thickness from 1dp to 2dp. Fixes LP: #1602690.
  * Add a snippet about tests to the toplevel README
  * Enter/Return to trigger, Space to expand ComboButton. Fixes LP: #1523817.
  * Initialize engine variable before using it in the _engine case.
  * Use Qt.rgba instead of #0000 checking ListItem default color.
    Fixes LP: #1560004
  * Don't use a different .desktop file in the gallery tests.
    Fixes LP: #1578319
  * Update scaling docs, set QT_SCALE_FACTOR and unset GRID_UNIT_PX.
    Fixes LP: #1610208

  [ Florian Boucault ]
