tidy -slides causes a seg fault with this file. Why?

I get a segfault using tidy when I process the attached. IT does not
cause a seg fault with other files I process.

I tried to run tidy under gdb, but got nothing much informative back. 
I'm running RedHat linux 7.0 and the rpm from which I installed Tidy
is:  tidy-4aug00-1
