Glitchy cactus item texture

The sides of the cactus item texture are not connected to each other.
I've only noticed this at the creative inventory.
It's not showing up always, hover the mouse around the decoration block page for a while.
The texture of the cactus block seems to be ok.
I think it's first appeared at snapshot 13w43a, but I'm not sure.
Sorry for my bad english... :S
