This bug was fixed in the package update-manager - 1:0.156.12

---------------
update-manager (1:0.156.12) precise; urgency=low

  [ Colin Watson ]
  * data/gtkbuilder/UpgradePromptDialog.ui:
    - Remove has_separator property from dialog_really_do_not_upgrade
      (deprecated in GTK+ 2.22, removed in 3.0).
  * debian/control:
    - Restore gksu dependency, needed by e.g. check-new-release-gtk
      (LP: #980637).

  [ Michael Vogt ]
  * UpdateManager/UpdateManager.py:
    - disconnect model and clear store before rebuilding the cache,
      thanks to Colin Watson
  * po/*.po:
    - updated to the latest launchpad (LP: #628157)
  * DistUpgrade/DistUpgradeController.py:
    - remove backports sources.list.d file again after its no
      longer needed (LP: #973717)
  * DistUpgrade/DistUpgradeController.py:
    - when checking for the backports, its enough to check is the
      set of the needed ones is a subset of the found ones (LP: #969182)
  * DistUpgrade/DistUpgrade.cfg.lucid:
    - release-upgrader-libapt-pkg-dev is not needed for the upgrade
      itself
  * remove skype from the removal blacklist
