iPhoto 4.0.1 Problem: Can't Get Around These Damn Corrupted Files

So I still can't figure out what's up with iPhoto 4.0.1. I tried everything I could find on the web, and I still keep getting a batch of whacked-out corrupted files. Not sure what the heck they are.

And I found something else that was kind of odd... The iPhoto upgrade, despite having a bunch of weird files in it, still had more total files in the library and the same exact library opened in the last version of iPhoto. Are those corrupted files perhaps not photos at all but some other conversion gobbledygook?

I've resolved to just go through iPhoto photo-by-photo to make sure I'm not loosing photos, since I can't seem to be able to figure out any better way to do it. I would love to be saved so if anyone knows how to avoid this let me know.
