Spotlight in 10.5.5 no longer indexing iPhoto 08 content

Question

Problem: This used to work in OS X 10.4.11 and iPhoto 08: In iPhoto provide a comment for some photos. In Spotlight search for those photos by providing keywords from the comments. Spotlight finds the photos, and when I click on one of them iPhoto opens and the photo is selected.
Subsequently I did a clean install of OS X to 10.5.3, updated to 10.5.4, and installed iPhoto 08 from the iLife 08 CD/DVD, then placed a copy of my iPhoto Library in my Pictures folder. I was able to find commented photos using Spotlight.
After updating to 10.5.5 this no longer seems to work. That is, I can still find photos in Spotlight that I could find before updating, but new comments don't seem to be indexed. I have tried modifying the metadata of all 6,000 photos by assigning them a keyword, shutting down iPhoto, waiting, restarting iPhoto and removing the keyword. I have tried reindexing both the whole harddisk and just the Pictures folder (by placing them in the exclusion list, then removing them), but that only made the situation worse. Spotlight no longer finds any photos in iPhoto. I have even tried removing all /.Spotlight* files from the harddisk and reindexing using the Terminal. The commands are performed, but the result is the same. Mails and other documents that require import plugins are found in Spotlight, so this seems to be very specific to iPhoto (08).
Does anyone with the same setup (10.5.5 and iPhoto 08) have no/the same problem? Can anyone suggest a solution. I have reported this to Apple, but have received no reply.
Regards,
Richard
