iPhoto doesn't show most of the Faces in the Confirm Additional Faces dialogue
The latest (2013) version of iPhoto is doing strange things when tagging Faces.
I have several dozen people identified in Faces but with the new version (on Mavericks), when I go to the Faces screen the pictures for each person have been replaced with black squares.
When I double-click to add more Faces tags, then click on the Confirm Additional Faces dialogue, most of the pictures that are proposed for tagging are also shown as black squares. A few of the images will actually show the faces that iPhoto has identified, but most of them are black squares and therefore rather impossible to tag!
Hopefully Apple will pick up on this bug and fix it ASAP. Thanks!
