ToME: the Tales of Maj'Eyal

Every time I try to create a game, I crash at about the 62% mark. The end of my log file reads:

Lua Error: /engine/Birther.lua:46: /engine/Birther.lua:46: /data/birth/worlds.lua:63: attempt to index global 'Birther' (a nil value)
At [C]:-1

I can post the full thing if you need more. Any ideas how to fix this? I am dying to give the game a go.

Does this happen if you disable all addons in game and then try?

Just to respond for the OP: I had this exact same stack trace, and disabling all add-ons fixed the problem.
