Interesting. I e-mailed you off-list about some other problem I observed
at least here, but this sounds like a simpler thing.

I looked in the VML file I got here:

<taggroup name="information">
	<tag-uint32 name="vertex_count">23370</tag-uint32>
	<tag-uint32 name="poly_count">22782</tag-uint32>
	<tag-uint32 name="mat_count">42</tag-uint32>
</taggroup>

That looks correct, or at least plausible. So I looked at the loader's
tag loading code. And sure enough, there was a bug! :) I've committed
the fix, please try it now.
