[Launchpad Bug Tracker <926979@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package unity -
7.2.5+14.04.20150521.1-0ubuntu1

---------------
unity (7.2.5+14.04.20150521.1-0ubuntu1) trusty; urgency=medium

  [ Chris Townsend ]
  * Releasing 7.2.5.
  * Bump version to 7.2.5.
  * Use a 2 second delay before showing the first run shortcut hints to
    workaround a race condition on input handling. (LP: #1313597)

  [ Andrea Azzarone ]
  * Add the possibility to specify the font size and the font weight
    without chaning the default font name. (LP: #886478)
  * Do not restore focus if a quicklist is opened during launcher key
    navigation. (LP: #932486)
  * Draw osk above unity shell. (LP: #1413165)
  * Forward first key event that happens on top of the blank window to
    the lockscreen. (LP: #1308265)
  * Make sure scope_views_[filter.id] exists before using operator[] on
    it. (LP: #926979)
  * Release pointer barrier if launcher is in lock_hide state. (LP:
    #1029114)

  [ Brandon Schaefer ]
  * When we quit the quicklist it would check if the mouse was over the
    launcher, if it wasn't it would fold the launcher. We don't need to
    check this if we are in keynav as we want all the icons to be
    unfolded. (LP: #1246891)

  [ CI Train Bot ]
  * New rebuild forced.

  [ Stephen M. Webb ]
  * AP tests: accounted for arbitrarily-raised exceptions in checking
    scaled windows (LP: #1436095)
