It's not a glitch... it's an easter egg, the programmers put it in there intentionally, just like the Cheat Node in KotOR 2... when I found it the first time, I just wondered why Zaalbar was following me around the ship and a Clone-Zaalbar was standing right next to him, then I found the Galaxy Droid and thought something happened to my Xbox, then I shut it down. It was VERY freaky...
