I personally don't care. I'm not affected by the bug with my almost non-existent "iPhoto collection" - I only use the app when I wanna upload images to my facebook account. These are images that I don't need to retain the original high-def versions of. I'm not a photographer.
Yep, it's because being me, I'd like to be always up to date :D
Download the latest iPhoto '11 9.0.1 Update from Apple's site. Or just run "Software Update".
And while you're at it, be sure to install Java for Mac OS X Update 3 too.
