vanilla "casting" crash

Whilst this bug does not occur naturally in Vanilla SMP, it affects unmodded vanilla CLIENTS playing on bukkit servers.

The error occurs turning a GlassBlock into a ChestBlock.
It appears to only occur when the blocks being changed are ocurring outwith of the immediate proximity: in one of the chunks that doesn't receive immediate update.

I haven't encountered this with glass turning into other blocks except Chests, nor have I extensively tested this with other blocks turning into chests.
I can reproduce this, should require it you can contact me at ctrgoudie@gmail.com
I can also produce a short youtube video should you prefer.
