I am getting frequent crashes when using the Combine Overlaps command.
Sometimes it works, sometimes it doesn't, but when it doesn't it is
reproducable with the same model consistently, thereby preventing me from
making forward progress with my work. Heres the crash log that it
produces:

"Yet mark his perfect self-contentment, and hence learn his lesson,
that to be self-contented is to be vile and ignorant, and that to
aspire is better than to be blindly and impotently happy."
