Version 1.7.5. : Create reports from testcase generates an error

When i tried to create a report from the last run of my testcase, i
got an error.

javax.xml.transform.transformerException: java.lang.illegalArgumentException: argument type mismatch.

This error occurs when i click on the 'OK'-button.

I use C:\Program Files\Java\apache-ant-1.7.0

This occurs in SoapUI 1.7.5 beta1 Pro

if you need more information, then ask for it.
