I wonder if this will break something new... 😉
5.0 gave us new features but could corrupt iPhoto 4 libraries on import
5.0.1 fixed the import from iPhoto 4 bug but made large libraries unstable
5.0.2 fixed the instability but gave us the colour shift bug
5.0.3 fixed the colour shift bug and gave us the weird crash/duplicate of rotated images when imported
Weird though how you wait 2 months for an iPhoto update and then 2 come along in a week or so...
