Hello, I can not reproduce the bug: I've tried this example [*] (since it is a file from "examples" folder, you may just refer directly to it, so that we're sure it has not been altered) with two recent versions (2016-10-31 .git-1b22b1a and the last one 2016-12-20.git-54c46f3) and did not get any crash.
I'm marking thus the bug for now as "invalid", before any new information. You may give us copy of the whole YADE output when you launch this script, for instance.
