This bug was fixed in the package update-manager - 1:0.152.12

---------------
update-manager (1:0.152.12) oneiric; urgency=low

  [ Michael Vogt ]
  * AutoUpgradeTester/UpgradeTestBackendQemu.py:
    - add NonInterative/AddRepoUpgradeImmediately option that allows
      installing test package *before* the test upgrade runs (useful
      for e.g. testing a new apt or dpkg)

  [ Robert Roth ]
  * Added default value to be able to start UpdateManager without
    having gir-unity installed (LP: #823935)
  * Fixed changelog test with the new wording
  * Specify default -1 length for terminal response (LP: #817785)
