Photos creates placeholders for deleted files.
Submitted by Mohammed Sadiq
GNOME photos creates placeholders for images that are deleted, but whose details are present in tracker.
It spits the following warnings to stdout too (in my case): ** (gnome-photos:24040): WARNING **: Unable to query info for file at file:///home/sadiq/Downloads/design.jpg: Error when getting information for file '/home/sadiq/Downloads/design.jpg': No such file or directory
GNOME photos should just ignore such files that doesn't exist anymore.
