I wasn't able to reproduce this, but opening a door/game server lagging combination made me clip inside a building's textures and I got stuck. Luckily fooling around with jumping/running freed me. At least the doors aren't lethal now!
Moving the player automatically from the door when opening it would be problematic since it could cause all sorts of random movement, I really don't know how I would solve this clipping issue. Remove door animations? 😈
