Title:
  Software Updater window is invisible

Status in update notifier:
  New
Status in update-notifier package in Ubuntu:
  Confirmed

Bug description:
  The software Updater icon has just appeared in my Launcher (it's
  probably trying to tell me that there are updates available, but who
  knows really). However, the window cannot be accessed in any way.

  By clicking on the launcher icon, a small arrow appears on the right
  of it, and the title "Software Updater" appears on the top screen
  title bar (see screenshot), but no window becomes visible.

  By hitting Alt+Tab, Software Updater is not even in the list of the
  available windows: this is an inconsistency that, no matter whether or
  not there's a bug in Software Updater itself, reveals a lower level
  bug in Unity (or whatever system component is responsible for
  switching windows), as there must ALWAYS be a 1:1 correspondence
  between open windows listed in Launcher and windows available via
  Alt+TAB.

  I don't know whether this is related to bug #1671529, but there is a
  difference (I'm almost sure of): in the case of that one the window
  was available via Alt+TAB, though it wouldn't show up if selected.
