There's a revision to the branch, but I think I'd prefer to experiment
on utopic users before attempting trusty again.

Title:
  hud-service crashed with g-assert-if-reached in GMenu call from
  qtgmenu::QtGMenuModel::CreateChild()

Status in “hud” package in Ubuntu:
  In Progress
Status in “hud” source package in Trusty:
  Fix Committed

Bug description:
  [Impact]

   * Unknown GTK application causes HUD service to crash by sending
  invalid menu updates via GMenu.

  [Test Case]

   * Not reproducable so far.

  [Regression Potential]

   * Worst case is that somehow HUD doesn't work on the desktop and
  phone.

   * There are, obviously, extensive unit and functional tests to verify
  this doesn't happen.

  [Other Info]

   * The patch will report the offending application to
  errors.ubuntu.com with all available debugging information.

   * The indexes are now range checked before processing. As soon as a
  window sends any invalid message it is blocked.

   * Further hardening around the memory management in QtGMenu has been
  carried out.

  * The change is not as large as it at first appears. The majority of
  the diff is simply replacing Type* with QSharedPointer<Type>. The rest
  is the extra code for reporting the recoverable problem.
