[PATCH] - Information-Sidebar should display informations about the selected object (bug 122045)

[Vincent Noel <vincent noel gmail com>]

Hey all,
here is a patch to fix bug 122045 - 
Information-Sidebar should display informations about the selected object
http://bugzilla.gnome.org/show_bug.cgi?id=122045

With this patch, the information sidebar shows information about the
current selected object (or the current opened folder if nothing is
selected). If several objects are selected, the last selected object
is displayed (this is non-optimal but can be improved later...)

I had to make one function public in nautilus-information-panel.

Please comment

Cheers
Vincent
