Comment 17 for bug 751374

The bug seems to be that Nautilus cannot open a URI beginning with "file:///" that includes a filename at the end. Here's how to easily reproduce the bug:

1. Install Thunar (which does not have this bug).

2. Choose or create an arbitrary file (say, from LibreOffice Writer), let's say "/home/myuser/Documents/foo.odt"

3. Can Nautilus open this file for us, if we pass a "file:///" URI to it as an argument? Open a Terminal. Ctrl+Alt+T.

4. Try opening the file with this command to see the error dialog appear:
      nautilus file:///home/myuser/Documents/foo.odt

5. Now do it again, removing the filename off the end:
      nautilus file:///home/myuser/Documents/

      ...and now Nautilus will open that folder! So it's proven that Nautilus doesn't like the filename on the end of the URI.

6. Let's try step 4 again, but this time with Thunar:
     thunar file:///home/myuser/Documents/foo.odt

     ...and now Thunar will properly open the file directly into LibreOffice (like Nautilus should). Bad Nautilus!

7. As a workaround, set Thunar to be Unity's default File browser, with the command:
     exo-preferred-applications

     ...then go to the "Utilities" tab, and set the File Manager to "Thunar," and "Close"
