On page 503, in the chapter "The Dream" where Harry goes to Dumbledore's office and stops outside because Moody, Fudge, and Dumbledore are talking, it says:
(Fudge) "Dumbledore, you know what that woman IS?"
"I consider her to be a very able Head-mistress- and an excellent dancer,' said Dumbledore quietly.
"Dumbledore, come!" said Crouch angrily. Then, in reply, Dumbledore says "I think it is possible that it is you who are prejudiced, Cornelius."
But Crouch wasn't there in the first place! He was at his house, or perhaps by then he had run away, but he was NOT in Dumbledore's office. Anyways, if this has been corrected in other books, feel free to post, but I noticed it in mine and it wasn't on here so I thought I'd add it.
