Exception when validating XML files

Attached is a project which chokes when calling QXmlSchemaValidator::validate.

Project must be extracted to C:\Support\XMLValidation to work out of the box. If not, two hard coded paths must be changed.

In Qt 5.1.1, this exception does not seem to occur, however the assigned UriResolver handler is not called. This is another bug which probably will show up. Next is the actual validation which does not work either. So this ticket is kind of a Kinder egg.
