Charset or Encoding problem with validator

I have discovered a probable bug in the system with validator.w3.org
Try validating www.exevior.com using this address: http://validator.w3.org/check?uri=http%3A//www.exevior.com
I have checked the server and don't think it is an issue with server parsing as other websites on that server validate correctly.
Checked my encoding, markup tags e.t.c. and all seems to be fine, even the same with the other sites that validated.

I also checked the WDG validator and that validates correctly. http://htmlhelp.com/cgi-bin/validate.cgi?url=http%3A%2F%2Fwww.exevior.com&warnings=yes&input=yes

Could this be a bug in the system that is worth reporting in bugzilla?
Or is it something related to any other server settings, home directory specifics for example e.t.c.

Any suggestions are welcome.
