Comment 1 for bug 32873

I am on dapper and can reproduce this:

Steps to reproduce:
(ensure that openssh-server is installed and sshd is running)
1. Go to Places -> Connect to Server...
2. In the dialog that pops up ensure the service type is SSH and type localhost into the Server box. Click Connect.
3. A dialog will appear, prompting for your password. Enter it and click Connect.
4. A nautilus window should appear with "sftp: localhost on localhost" in the title. Within this window go to Places -> Add Bookmark. Close the window.
5. In a terminal use sudo to become root and run ifdown lo .
6. Press the right mouse button over a bit of empty panel at the top of the screen and go to Properties.

Expected results:
The same result as if there were no bookmark - a Panel Properties window to appear, panel to remain responsive.

Actual results:
No Panel Properties window appears and the panel becomes unresponsive.

Additional information:
Doesn't appear to happen with things like an annoymouse FTP bookmark when the external interface is brought down. Removing the bookmark makes the problem go away - it has nothing to do with the share (which can be unmounted/removed but so long as the bookmark remains so will this problem). Bringing down the loopback device does not normally cause a problem displaying the properities box.
