Comment 3 for bug 952108

This is what I did:
 * I installed nautilus-dbg
 * Closed nautilus: nautilus -q
 * Opened nautilus with valgrind: G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind -v --tool=memcheck --leak-check=full --num-callers=40 --log-file=valgrind.log nautilus
 * Opened a directory where a video file was being downloaded (and Nautilus regularly refreshed its preview)
 * Opened a directory with a lot of other directories
 * Opened a directory with a lot of music files
        Nautilus gives us a lot of error like that:
          totem-video-thumbnailer: 'file:///path/to/a/mp3/file' isn't thumbnailable
          Reason: Media contains no supported video streams.
 * Kill Nautilus with <Ctrl> + C

Thank you!
