items caught in nether portal

once the nether portal started working I found a strange bug. One time I entered the nether portal I ran into some lava, tried to escape but died as I reached the portal, an item I was carrying at the time got caught in the portal, now every time I join the game they and 3 buckets which got caught at a later time are there for me to pick up. If I pick them up leave the game and return to it they are there again. I can pick up 2 netherrack and 3 empty buckets over and over again probably until I can carry no more of them. I would attach a screen shot but am having trouble making them.
