Changing your name to "Leader of the Chaotix" causes the game to absolutely shit itself

I seriously don't know how to describe this.

Changing your name, while in a server, to "Leader of the Chaotix" and setting your skin to Knuckles using the ingame menu causes the game to crash (sigsegv). Using this name also causes the game to overwrite your config file seemingly at random or cause crashes. What the fuck.

Other long names and skin combinations can cause a crash as well.
