Comment 4 for bug 600388

I don't sure that this problem is caused by nautilus.
I have activated Cover Thumbnailer with my music folders.
In some folders, containing a "folder.jpg" image file, CoverThumbnailer shows the CD image but no with the cover image. See screenshot attached. And though I close and reopen nautilus, it still doesn't work. I have to close nautilus completely, with "nautilus -q", so it shows me the cover properly.
I wrote a script (in bash) so that my folders of movies showing the cover, and it works well. I use the next command:
                        gvfs-set-attribute "<folder>" metadata::custom-icon <image>

By this reason, I think that the problem isn't in nautilus.
