This bug was fixed in the package unity - 7.1.2+14.04.20140228-0ubuntu1

---------------
unity (7.1.2+14.04.20140228-0ubuntu1) trusty; urgency=low

  [ Chris Townsend ]
  * Use the current Launcher instead of the first launcher when
    determing when to highlight the Launcher tile during keynav. (LP:
    #1285361)
  * Fix Dash/Hud fullscreen Autopilot window test on multi-monitor where
    the tests would fail depending on which monitor has the fullscreen
    window. (LP: #1285367)
  * Fix a couple of Panel Autopilot test failures. (LP: #1285737)
  * Fix a few randomly failing Spread Autopilot tests. (LP: #1285758)
  * Fix corner case depending on where a test window opens, a Dash and
    Hud Autopilot test failure can occur. (LP: #1286143)

  [ Stephen M. Webb ]
  * remove -O3 and replace with -O3 for C++ compiles to prevent
    template-related FTBFS (LP: #1286284)
