Ubuntu Hardy Heron 8.04 amd64 / x86_64
alpha / beta updated
I used places > connect to server to connect to an sftp (SSH) connection.
The first time it connected fine, but then all of the sudden it stopped responding, I closed nautilus then.
Now I can't unmount it. After some time I get an error saying this:
Unable to unmount sftp on example.com
DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
Also, I can't connect to it either:
Couldn't display "sftp://user@example.com/".
Error: DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
Please select another viewer and try again.
Connecting to the server looks ok from the command line though:
$ sftp user@example.com
Connecting to example.com...

Ubuntu Hardy Heron 8.04 amd64 / x86_64
alpha / beta updated
Note: Everything below happens with ftp (with login) option as well.
Note 2: I think nautilus affects this bug as well. The weird thing about this bug is that it doesn't happen always, therefore I also think nautilus (or something) "caches" or stores the retrieved list of contents of the server folder. Use a new username or server to test this, because when I re-added the 'connect to server', the new window and the connection were ok if I visited previously browsed folders from previous connections, but when I went to a folder or a username that I haven't visited or used before, the window or the connection do not respond and the list of contents of the folder is not shown.
Note 3: As I stated in note 2, we have two situations, one with a greyed out unresponsive window and one with a responsive window (being able to close without "force quit") but with a mouse pointer as "waiting". From what I've tested, they're randomly produced with the steps I explain below.
Note 4: If I hit ctrl-L and enter sftp://user@example.com/home/user/ everything is normal, I can also unmount it normally. Only sporadically do I get an unresponsive greyed out window (see note 2). I have to kill the (two) processes related to the sftp connection in order to use it.
Note 5: In my opinion, something goes wrong while it tries to get the list of contents of a destination / folder.
I used 'connect to server' to connect to an sftp (SSH) connection.
Menu Places > Connect to Server
Type: SSH
Server: sftp.example.com
Port: (left blank)
Folder: /home/user
User name: user
Add bookmark: checked
Bookmark name: mysftp
When I hit the connect button, it pops up a new nautilus window, trying to browse the sftp. That's when the problems appear, and I end up with an unresponsive window, probably when it's trying to retrieve the folder's contents. Sometimes the window can be closed (although the mouse pointer is "waiting"), or I have to use the "force quit" option it gives me for nautilus, see note 3.
That very first new window that is automatically opened after hitting the connect button seems to mess up the whole connection.
I'm saying this because I killed the two processes related to this and connected through the sftp bookmark, which was created previously (using 'connect to server'). I used the menu Places > Bookmarks > user (the name of the bookmark), it opened a new window and I could browse my server with no problems. This success could be related to a cached list of contents, see note 2.
Some errors I come accross:
1) If I leave the window (with the mouse pointer as "waiting") open for several minutes, it eventually returns an error:
The folder contents could not be displayed.
Sorry, couldn't display all the contents of "user": DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
2) Trying to unmount using the side pane, I right click on the sftp virtual filesystem and select unmount. After some time I get an error saying this:
Unable to unmount sftp on example.com
DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
3) If I close the nautilus window and open a new one, then double click on the side pane to show the sftp:
Couldn't display "sftp://user@example.com/".
Error: DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Connecting to the server looks ok from the command line:
$ sftp user@example.com
Connecting to example.com...
Password:
sftp> ls
[...]
sftp>
The connection is established as netstat outputs:
$ netstat -ep | grep ssh

$ ps ax | grep -i sftp
