Game crashing when entering the pocket dimension

For one of my characters, every time I enter the pocket dimension the game crashes. This is the second time I've come across this bug, but the first time I played around might be. I guess I can play on without the pocket dimension (like old times!) but I've got some crafting materials in there I don't want to have to farm again from scratch. Grrr.

I uploaded a copy of the save just in case it's any help.

EDIT: Sorry for posting in the wrong place, I only just saw the bug reports thread :/
