--- Comment #6 from MarcP <iwannaber...@gmail.com> --- Ok, I finally found out what was happening, because sometimes when deleting faces changes were saved, and other weren't. It turns out the problem only arises when there is a duplicated face rectangle in a picture. In my case, I was deleting duplicated face rectangles that appeared as a consequence of re-scanning the images when Bug 372340 was present, so everyone had two face rectangles, a "landscape" one, and a "portrait" one (because of the incorrect rotation of the picture), where one of them was usually pointing at the sky or another background element. Let' say there are two Person 1 and one Person 2 rectangles in an image (use attached file as an example). If you delete the face of Person 2, changes will be written (Item/re-read metadata, just to confirm this). If you delete a face of Person 1 (any of them), changes will NOT be written (if you re-read the metadata, the face will reappear). Having the same person twice or more times in a pictures is not common, but it can happen. For instance, someone looking himself at the mirror, or a photo with a framed picture of that person in the background.
