Please describe the problem:
When a directory on a remote host is mounted using the sshfs command, non-empty directories inside the mounted directory can't be deleted in Nautilus (as opposed to being moved to Trash) even when the user performing the operation has all the necessary permissions to do so.

Steps to reproduce:
1. Start Terminal, create mount point somewhere inside current user's home directory (e.g. ~/mnt/mountname).
2. Mount home directory of same user on remote machine in LAN using sshfs (e.g. sshfs hostname: mnt/mountname). If required, confirm authenticity and enter password.
3. Create a new temporary directory (mkdir mnt/mountname/temp) and some file(s) inside it (ps >mnt/mountname/temp/ps.txt). Using ls -l, make sure the temporary directory and file(s) exist and have write permissions for the current user.
4. Open Nautilus, go to the temporary directory, select it, try to delete it using the (optional) Delete option in the directory's context menu or by pressing Shift+Del.
5. A dialog box with an error message appears in Nautilus: "Error while deleting. There was an error deleting mountname." Choosing the "Show more details" option will reveal the following text: "Error removing file: Operation not permitted."
6. Go back to Terminal window. Delete temporary directory with temporary file(s) inside it using the rm command (rm -r mnt/mountname/test). The directory and all its contents will disappear without any errors.
7. OR, in Nautilus, first delete the file(s) inside the temporary directory so that it is emptry, then delete the directory itself.

Does this happen every time?
Yes.

Other information:
I'm using Ubuntu 8.10, amd64 and i386 versions, on three different machines, all of them showing the issue described above. The problem was already present in Ubuntu 8.04. As a workaround, I have created a simple Nautilus script that allows me to delete any directory (empty or not, remote or local) via its context menu.
