[Cosimo Cecchi <cosimoc src gnome org>]

commit 518a1ae6ba0a3e09236f944ee655334087d5ddee
Author: Cosimo Cecchi <cosimoc gnome org>
Date:   Thu May 28 11:43:14 2009 +0200

    Display information about the selected object
    
    Display information about the selected object in the "Information"
    sidebar, using thumbnails if possible.
    Also, remove the "Open with" buttons there for directories.
    Fix bug #122045, thanks to Amos Brocco.
