Crash opening files

In a XP box with Corel Draw Graphics Suite X6 we are getting repeatedly the following NET Runtime exception on opening files:

Aplicación: CorelDrw.exe
Versión de Framework: v4.0.30319
Descripción: el proceso terminó debido a una excepción no controlada.
Información de la excepción: System.AccessViolationException
Pila:
   en <Module>.ManagedWPFTypography.ShapingOutput.Clear(ManagedWPFTypography.ShapingOutput*)
   en <Module>.ManagedWPFTypography.ShapingOutput.__vecDelDtor(ManagedWPFTypography.ShapingOutput*, UInt32)
   en WPFTypographySvcImpl.InternalDispose(Boolean)
   en WPFTypographySvcImpl.Dispose(Boolean)
   en WPFTypographySvcImpl.Finalize()

The designer who uses the suite has told me that he thinks this happens with cdr files that have images cute/pasted from Adobe Illustrator.

Any clue about what is wrong?
