Error while loading chunk on first run

[SpaceManiac]

<kookster> first run
<kookster> i opped myself
<kookster> then i set my gamemode to creative
<kookster> started flying

Presumably the chunk shouldn't have even been written yet, so it's odd to see an error loading it.

I have got the same bug but with [GRAVE] flag. It happened when I was walking towards the horizon.

Any possible information on this? World files?
