blender2.4 crashes when wire and build used together

I have human object that i imported from makehuman (LAstest version) i am using blender2.4 The material of the human object is wire. Under add modifiers I have picked build (to build the object). When I select wire and build together and try to animate Blender crushes. The Alt-A option isfine. When I animate wire and build seperately everything is fine. When I replaced the human object with a box mesh without using the same settings blender does not crush.

So is the there a bug when using the object imported or is something else I need to do?

An advanced Thanks for your guys’ help :expressionless:

So has any had this problem? :frowning:
