Yeah, but doesn't tell me much. It looks like it's crashing on data in 
the locatedb file, not while doing anything else.

I suppose it could be dying because of a particular file or directory on 
your filesystem that results in a db entry it doesn't like - which would 
explain the fact that removing locatedb doesn't help. Perhaps it can't 
handle ultra-long paths or some character in a filename?

I can only suggest finding a newer version of locate, if possible, or 
hunting down slocate. Otherwise - well, it's time to get to know gdb :-/
