Well I was dragging 4 on the picture but it only appears when you run out of items. For example if you have 13 items when you get to 0 left it displays 47e0. Sorry but I can't get a video version. It happens everything you get to 0 items when dragging.
Here is a picture:
The left is leather armor not dyed and the right is iron armor.
I have tried with 1.7.2 vanilla minecraft and the bug is not there.
Btw I have no mods in my mod folder
