Yes iPhoto 09 works fine on Mavericks. Was using it for the past 4 weeks since upgrading to mavericks without any issues. Have now upgraded to the current version through the mac app store.
The new edition of iPhoto dumps the library sharing of the old version and forces you to use iCloud. Yuck, but some may like it. I consider that "broken," but that's just my opinion
