  -------

  I am using AppIndicator via Python. On Ubuntu 12.10 (stock install,
  python-appindicator: Installed: 12.10.0-0ubuntu1) when I listen for
  scroll event signals, the direction is always reported as UP, never as
  DOWN - even when scrolling down. This was working on 12.04.

  My application variety depends on this functionality, here is the
  relevant bug report for it:
  https://bugs.launchpad.net/variety/+bug/1071598

  Here is sample code to demonstrate the problem (OK on 12.04, buggy on
  12.10):

  from gi.repository import Gtk, Gdk, AppIndicator3

  if __name__ == "__main__":
      menu = Gtk.Menu()
      quit = Gtk.MenuItem("Quit")
      quit.connect("activate", Gtk.main_quit)
      menu.append(quit)
      menu.show_all()

      def scroll(ind, steps, direction):
          print steps, direction
          if direction != Gdk.ScrollDirection.UP:
              print "Things seem ok"

      indicator = AppIndicator3.Indicator.new('testscroll', '', AppIndicator3.IndicatorCategory.APPLICATION_STATUS)
      indicator.set_status(AppIndicator3.IndicatorStatus.ACTIVE)
      indicator.set_icon("/usr/share/pixmaps/firefox.png")
      indicator.connect("scroll-event", scroll)
      indicator.set_menu(menu)
      Gtk.main()
