I had to recover a RM9 corruption by restoring from a backup. After restoring, all the media links were broken (as expected) and I dutifully ran the fix links tool, immediately exited from RM9, came back in and hey presto received the Tabulmage error reported here. By trial and error I found that fixing the media links was the cause of this problem, and further it was a problem only after I restored the media folder that contained all the primary people images. So I repeated the restore process, but after fixing the media links but before exiting RM9, I opened a few images (not the thumbnails) of people’s primary image. My Mac showed some strange displays of the person image but after 15 seconds settled down and showed the person image as expected. Then when I came back in to RM9 there was no Tabulmage error !! It looks as if you have to let the Mac/RM9 adjust to the new person images and then it knows what to do in future.
Anyway - just thought this might help others if they get hit with the dreaded Tabulmage problem.
