We were not able to open the url for some reason, but we have encountered and fixed similar bug, that manifested itself only when having subreports items that do not fit on a single page. Can you confirm that this is the case? If so the good news is that it has been addressed and would be part of the SP1 scheduled for the end of the week.
If you think this is a different issue, please open a support ticket and provide us with a sample report showing the problem.
