The new package version which should fix this bug seems to have included
a typo in the version number.

+hud (14.04+14.04.20140604-0ubuntu1) trusty; urgency=medium

Notice how the package version number starts off with 14.04 instead of
13.10.  Was this intended? If so then the version number for Trusty will
be greater than the one for Utopic.

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:
  In Progress

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.
