How to refresh nautilus thumbnails?

["D. D. Brierton" <darren dzr-web com>]

Where does nautilus store thumbnails? How can one refresh/regenerate the
thumbnails? For instance, the previous version of totem I had installed
from freshrpms.net wasn't managing to generate thumbnails for movie
files. However, the latest version does. So new movie files get a
thumbnail, but all my existing ones just have an icon. I'd like to
persuade nautilus/totem to generate thumbnails for the existing clips I
have. I assume the easiest way would be to delete some config file, or
some line in a config file, but I haven't been able to find anything by
searching trough the various dotfiles in my home directory. There is no
.thumbnails or .nautilus-metafile.xml in the the directory containing
the clips.

Any pointers?

TIA, Darren
