An interesting topic. I just castled on move 16 in my game with GKChesterton, even with my i-pawn removed and the Black Queen capturing onto h3 on the next move! Clearly dangerous for white, but with a lead in material, I could bait this attack then defend easily in later moves. So this is a rare instance of castling deliberately into a 1-move danger situation with a long terms benefit.

Of course at http://www.geocities.com/bow_of_odysseus/deadly_arch.html there are some examples of some castling blunders if you need to see a concrete example of some.

Personally, I have not made up my mind about this as of yet. Castling too early can be deadly. Not castling at all can be deadly, and castling too late can be deadly!

The best solution is to checkmate your opponent before you castle so you don't have to worry about castling!
