Crash dump when trying to rotate object

[w3dut]

I installed the newer version and ran the cleanup command. That stopped the crash, however the model was flawed. It has 'holes' or 'see through' areas that I couldn't seem to figure out how to fill and some 'artifacts' that are way off the surface of the model that I can't seem to move or delete. So, I started over with a different model.

Thanks for the help, I appreciate it.
