crash... bug in XSV attributeGroups code?

I'm not sure there really is an automated mail message
to the maintainers, so... I'll send this here...

I'm trying to validate a mathml-in-xhtml document:

http://www.w3.org/XML/2000/04schema-hacking/xhtml-mathml-ex.html

the schemas each check OK:

	http://www.w3.org/XML/2000/04schema-hacking/html-renamed
	http://www.w3.org/XML/2000/04schema-hacking/mathml-renamed

but when I try to check the example document using
	http://www.w3.org/2000/06/webdata/xsv
I get:

The maintainers of XSV will be notified, you don't need to
send mail about this unless you have extra information to provide.
If there are Schema errors reported before the crash, try correcting
them and re-running the validation.
