Title:
  Modal dialogue from update-manager does not appear in unity's spread,
  leading to confusion

Status in Unity:
  Confirmed
Status in “unity” package in Ubuntu:
  Confirmed
Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:
  - Open update-manager at a point in time such that you get the "Not all updates can be installed" dialogue (surely there is a way to trigger this by hand, and there must be a different application that exhibits the same behaviour)
  - Move this modal dialogue to a different desktop
  - Return to the desktop where update-manager's main window is
  - Try to interact with the window - it will ignore clicks (as it should) [1]
  - Eventually realize that there are two arrows next to the update-manager icon in unity's launcher, so click on the icon
  - Spread mode is triggered, but only the main window appears [2]

  What should happen instead:
  - Spread mode is triggered and both the main window and the modal dialogue are shown

  Notes:
  [1]: this is the real problem here, but this will be fixed with the introduction of the modal dialog plugin in oneiric+1
  [2]: spread is not triggered when there is only one (regular) window of an application; in this case it looks like it's trying to do the right thing by allowing spread in the first place, but then it fails at actually displaying the window
