Jordy, just because you don't like something doesn't mean you get to silence discussion of it. That, and glitches can't be FIXED unless they have been reported. (Ninja'd, apparently)
I would say this was old news, except it doesn't appear to be, as the Minecraft Wiki says that it only generates one working door and one door that doesn't work.
When placed the door breaks, along with the cacti. This spawns two USABLE door pieces.
Works and tested.

I found a glitch or bug in the game. I reported it. Problem?
