Description of problem:
To change f.eg. permissions for more than one file at a time  (graphically, not
using chmod in a terminal) you have to be able to select several files at once,
right-click and set the desired permissions in the Permissions tab. However,
nautilus currently opens N dialogs if N files are selected, which forces you to
use the terminal for all types of actions that should affect more than one file
at a time.

Version-Release number of selected component (if applicable):
2.2.1

How reproducible:
Always

Steps to Reproduce:
1. Select a couple of files (two is enough) in nautilus
2. Right-click on one of those files and select Properties
3. Watch a dialog pop up for each file selected
    
Actual results:
Several dialogs are displayed

Expected results:
Only one dialog should be displayed where one could watch/set common properties
applicable to all files currently selected.

Additional info:
This is a must if we want Gnome to succeed on the desktop - no user (coming from
whatever other graphical DE) would accept returning to the command line to do
stuff like this. High priority, if you ask me! :}
