--- Comment #13 from foobard jens@porup.com 2008-04-16 18:14:46 --- Attempting to File --> Create PDF --> From Multiple Files produces the exact same msgbox error mentioned in the original report.
Or rather, you can create a new pdf from two existing pdfs, but when you try and save the resulting new pdf, you get the msgbox error "Unhandled page fault on read access...etc" error.
