description: see title
reproduce: break leaves with shears(have not tested other types of shears or leaves, it may just be oak leaves)
expected: get 1 leaf block per break
info: singleplayer beta 4 world

edit: seeing as there is a stack of 5 leaves of a different type, my guess is that it is an oak leaves issue

Since it doesn't seem to be reproducible, I'll close this.

cannot reproduce on dev singeplayer

does it happen on a new world and/or reinstall
