  * Add safety valve for DBusMenuCollector that also reports the
    offending application (LP: #1280372)

  [ Charles Kerr ]
  * Simplify the implementation of QtGActionGroup. This started off with
    the intent of removing the overhead of g_action_group_list_actions()
    in QtGActionGroup::Action(), but then I found
    QtGActionGroup::Action() was only called in the object's constructor
    and destructor, so it made more sense to remove the function
    altogether. Summary of changes:   * Plugged GVariant leak in
    QtGActionGroup::TriggerAction()   * Plugged char* leak in
    QtGMenuUtils::makeStringListQVariant   * ActionGroup ctor calls
    g_action_group_list_actions() once instead of n+1 times   *
    ActionGroup dtor calls g_action_group_list_actions() once instead of
    n times   * Removed unused public method Size()   * Removed newly-
    unused public method Action()   * Removed newly-unused field m_size
    (LP: #1296746)

  [ Pete Woods ]
  * Add null guards to ItemStore search (LP: #1292237)
  * Fix test failures exposed by fix to libqtdbustest (LP: #1296744)
  * Call only "safe" write method from UNIX signal handler See
