Hm, where is this check? In libnautilus-private/nautilus-thumbnails.c it
does a simple check on the mtime of the two files. Why do you want to
store the creation time of the original image in the thumbnail? In which
cases could a simple image.mtime < thumb.mtime check fail?

As Havoc suggested, I will prepare a first draft of a thumbnail
specification and post it here. Then we can base our discussion on this
paper.
