So, it's mostly that a bunch of us think that Dumbledore was acting remarkably out-of-character in the last section of the book, and that there were several things which didn't make any sense, like the boat which doesn't count Harry as a wizard even though it measures magical power, Ddore's wearing of the Evil Ring, and the "KILL ME" scene.
One explanation, the most interesting one, is that Ddore was being Influenced by the bit of Voldiesoul in the Ring.
