Still happens in 13w02a. Also, lighting on the hand seems glitchy. The hand keeps going dark and back normal all the time for no apparent reason, unless it's shaded by the clouds...

Just wanted to confirm that the problem persists in 13w02a here.
Since snapshot 13w01b every time I create a new world I spawn stuck with only way to get out being /tp.
Java version 1.7.0_09-b05, Win7 x64, Minecraft 13w01b snapshot
Seems OK for me in 13w02b. Created several worlds, spawned under leaves and there was no problem.
