Unless it crashed your game client/server, I wouldn't worry about it too much. I can't verify it as fact, but it just looks to me like a variable string being parsed by FritzET with info on the Bot named Aragorn and his particular behaviors, preferred equipment, etc.
The fact that it popped in as red text, may indicate it failed to load for some reason, or it may not mean anything at all.
It's a normal message that is displayed when the anything abut the client changes (like a skill level change). It shows up in red in this case because the last letter in the bots name is red
