[Bug 61817] Nautilus regenerates thumbnail previews when using symbolic link

[saads]

Public bug reported:

Binary package hint: nautilus

If I open a directory with many image or movie files for the first time,
you can see nautilus generating the thumbnail previews for that
directory because they appear slow enough for you to see it.  When you
visit the directory a second time, those thumbnails are cached and
stored locally so they do not need to be regenerated and they appear
instantly.

If, however, you create a symbolic link to that directory and then visit
it through the symbolic link, the thumbnails will be once again
regenerated.  This is visible because they appear slowly and CPU usage
goes up as if you were opening the directory for the first time.  You
can do this repeatedly for any number of symbolic links and it will
regenerate them each time.

Nautilus should recognise the destination directory of the link and use
the cached versions instead of regenerating them each time.

** Affects: nautilus (Ubuntu)

         Status: Unconfirmed
