This error occurs when XML::LibXML (libxml) tries to load its default
catalog, and hits the limitation we set for locations where it is
allowed to load files from.  We try to instruct it to not load the
default catalog, but for an unknown reason that doesn't work in all setups.

If you're running the validator with mod_perl, try without it.  Other
things you may want to try is to add the the default catalog path of
your libxml2 installation after the "Do not trap file URIs within our
jail" line in the "check" script (which is usually /etc/xml and that's
already allowed), but because you're hitting this issue it might be that
our catalog setup doesn't work at all on your system which then again
causes fetching of DTDs from the net everytime and that's going to be slow.
