The same type of action has resulted in being phased through walls in brick pubs as well, thouhg non-fatally. Some eating and drinking animations while in the vicinity of superimposed loot piles has also resulted in slight displacements of character. It may be that having stacked items in the same position is responsible for interfering with character placement when animations are started "on top" of such loot piles.
