Thanks for the report. The most important part of information is missing: what world? and what command-line did you use to cause the crash?

i tried it aswell with 3.7.9 - because i have an notebook with debian and it only works with 3.7.9 there..
any ideas...? it seems it has something to do with the world?

"Terminating app due to uncaught exception 'NSInternalInconsistencyException'" - i dont know where i have to catch this exception to get a better debug information.
