shows "loading" and waiting icon forever after access denied to remote samba folder

- open nautilus
- browse to a remote samba folder
- try to open a subfolder to which you don't have access

Observed behavior
-You get the error message: "The folder contents could not be displayed. You do not have the permissions necessary to view the contents of 'XXX'"
- The folder is apparently opened (meaning its name is shown on the top of the window or tab and you see an empty folder),
- the cursor shows the waiting animation forever, and on the bottom-right corner you see "loading" forever, until you click on the "X" to cancel the loading

Expected behavior:
- you should get the error message 'You do not have the permissions necessary to view the contents of "XXX"'
- you should keep seing the containing folder, there's no point in faking the opening of the folder if you're not going to be able to see its contents, ever
- as soon as the dialog with the error message appears, the loading/waiting animations should stop (or never start in the first place). There's no point to keep waiting forever something that will never happen under any circumstances, and to force the user to explicitely cancel an operation that has already failed
