Diodon was only listed once in the Startup Applications list. I disabled it and rebooted, Diodon did not start (no icon and no running process). Starting Diodon manually resulted in just one tray icon. After re-enabling Diodon in the Startup Applications and rebooting, I'm back to two icons. Baffling. I don't think it should matter, but I realized I should have noted that I am running Diodon so that it only stores clipboard items in memory.
