This bug was fixed in the package unity - 4.28.0-0ubuntu2

---------------
unity (4.28.0-0ubuntu2) oneiric-proposed; urgency=low

  * Cherry-pick some additional fixes:
    - fix a regression where transparency is setup on the panel (LP: #830949)
    - the wrong commit causing a crash was revert. Revert the revert and
      revert the right guilty commit.

unity (4.28.0-0ubuntu1) oneiric-proposed; urgency=low

  * New upstream release.
    - don't segfault in geis_configuration_get_value() (lp: #850623)
    - get focus on dash by pressing the super key first time after login
      (lp: #860805)
    - clicking on panel when dash is open no longer causes maximized window
      to raise (lp: #873100)
    - window management, alt-tab - After using 'show desktop' to minimise all
      windows, opening any new window also incorrectly restores all
      the minimised windows (lp: #871801)
    - compiz crashed with SIGSEGV in
      unity::switcher::SwitcherModel::DetailSelectionWindow() (lp: #834630)
    - compiz crashed with SIGSEGV in g_strcmp0() (lp: #832151)
    - compiz crashed with SIGSEGV in nux::BaseWindow::GetInputWindowId()

    - fix multi-monitor crashers (lp: #838128, #864037, #864784, #868120)
    - Fix SIGSEGV after SwitcherController desctruction (lp: #887465)
    - Fix for "right-clicking launcher when choosing a workspace causes
      quicklists to freeze" (lp: #791810)
  * debian/patches/add_postrelease_buildfix.patch:
    - add post-release fix to build in a clean env
