This bug was fixed in the package unity - 4.10.0-0ubuntu1

---------------
unity (4.10.0-0ubuntu1) oneiric; urgency=low

  * New upstream release:
    - unity task switcher (alt-tab, alt-down) shows empty spaces for iconified
      windows in window detail mode (lp: #828348)
    - compiz crashed with SIGSEGV in
      unity::DeviceLauncherIcon::OnStopDriveReady() (lp: #824093)
    - Dash performance issues with 'Active Blur' enabled (lp: #824890)
    - compiz crashed with SIGABRT in raise() when setting background
      to full color (lp: #829049)
    - Dragging from dash to launcher still doesn't work (lp: #824833)
    - .desktops dragged on to unity launcher will not be added to
       com.canonical.Unity.Launcher favorites unless moved in the launcher
       (lp: #830536)
    - application's menu shown when the cursor is a little left
      to window controls (lp: #820293)
    - Ubuntu Start launcher item should always start the dash with
      the Home screen (lp: #825034)
    - search spinner does not stop hence nothing can be launched with
      the Return key (lp: #824836)
  * debian/control: updated nux requirement
  * debian/rules: updated shlibs
