DevonThink Pro Office: Crash on importing AA Pro 8-edited PD

IT’s like the Subject states, normal PDFs import flawlessly with DT Pro Office, but on trying to import a File (actually a invoice) which was edited and saved with Adobe Acrobat Pro 8, Devonthink crashes hard on me…

Is Preview able to open the PDF document? Because I guess you’re using a PDF specification not yet supported by Mac OS X.
