Well I never said it was another internet forum, I said it was an internet forum - this one. Search you and you will see some folks fixed this issue with the 8.0.2 update.
To do a Rebuild:
Start with Download
iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, faces or places for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
If that doesn’t work: A Manual Rebuild
To create and populate a new library:
Note this will give you a working library with the same pictures as before, however, you will lose your albums, keywords, modified versions, faces, places and books, calendars etc.
In the iPhoto Preferences -> Events Uncheck the box at 'Imported Items from the Finder'
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library (Right Click -> Show Package Contents) on your desktop and find the Originals folder. From the Originals folder drag the individual Event Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.
