Crash when rendering new chunk. Looks like related to BoP village world generation. The client crashes every time when loading the save with the same error.

Other crash report: http://pastebin.com/5U3vUhx7 (almost the same)

Looks suspiciously like the last bug you fixed ;)

Mystcraft not updated to 1.6.4.

Oh well... Sometimes the mod works anyway. Guess not, in this case.
Moved the player with mcedit away from the chunk of death and everything works now. That's the cost of living on the bleeding edge.
Thanks for the prompt response.

I experience this in 1.6.4 without running Mystcraft at all.

The other mod making that bug would be Forestry.
