Just a guess, but TQRPDFFilter is probably related to Quick Reports and I imagine that it may be a non-visual component that is used to generate a PDF version of a report. Are you using a quick report component and if so, have any options to produce the report in PDF format been set? If so, have the required units been included.
The error occurs when the streaming system attempts to generate a component but a class required by that component is missing (ie there is no RTTI information available). As suggested, search for where TQRPDFFilter is defined and make sure that unit is used in the unit where the exception occurs.
If not,"search in files" for QRPDFFilter ... Maybe some code in any unit.

Maybe adding "initialization RegisterClass(TQRPdfFilter)" at bottom of one unit solves the problem
