I don't think I've seen this before, might be specific to Solaris. From the
stack trace, it's not sure that the problem is in lxml, as the error is
handled purely inside libxml2 up to that point.

I'd say you're safe if you don't use schematron (which most people won't
run into anyway). Could you try to reproduce this with 'xmllint' (comes
with libxml2) and the empty schema given by the test case?

	<schema xmlns="http://purl.oclc.org/dsdl/schematron" />

That would allow us to see if it's a problem with libxml2.

Thanks,

Stefan
