Question concerning the first Hobbit film (Extended Version)

So, has anyone here seen the extended version of the first Hobbit film? I notice that among its ratings reasons is "Fleeting Nudity", which kind of made my jaw drop. The LOTR films tried to avoid nudity, even where the books had it. (Case in point, Frodo's capture by the Orcs in Return of the King.) When that film came out, I worried how they would handle that part, and I was thoroughly satisfied that Frodo was not completely stripped naked.

So ... can anyone tell me why there's Fleeting Nudity in the extended version of The Hobbit: An Unexpected Journey? I'd kind of like to know what that's about before I see it.

EDIT: Nevermind, I found out. Apparently we see bare Dwarf backsides as they bathe at Rivendell. Wonderful. **sarcasm.**
