SSH tunnel fails to connect with username

[tsh]

Binary package hint: vinagre

if I specify user@host in 'use host as ssh tunnel', I get the following messages:
vinagre --gtk-vnc-debug
gtk-vnc: Expose 0x0 @ 1472,772
gtk-vnc: Started background coroutine
gtk-vnc: Resolving host localhost 5599
gtk-vnc: Trying socket 22
gtk-vnc: Protocol initialization
gtk-vnc: Closing the connection: gvnc_read() - ret=0
gtk-vnc: Error while getting server version
gtk-vnc: Doing final VNC cleanup
gtk-vnc: Requesting that VNC close
gtk-vnc: Requesting that VNC close
gtk-vnc: Releasing VNC widget

and a 'connection closed'. If I omit the username, I get a prompt for an ssh password, but with the wrong user for the remote machine. (Which is also running ubuntu 10.4).

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect 585566 and any other logs that are relevant for this particular issue.

I just tested this on Ubuntu 10.10, using vinagre version 2.30.2. I still experience this error, with the following output when the username is specified for the ssh tunnel:

vinagre --gtk-vnc-debug
(vinagre:3621): gvnc-DEBUG: vncconnection.c Init VncConnection=0xa0c5300
gtk-vnc: vncdisplaykeymap.c Using evdev keycode mapping

gtk-vnc: vncdisplay.c Releasing VNC widget
(vinagre:3621): gvnc-DEBUG: vncconnection.c Finalize VncConnection=0xa0c5300

apport-collect warned about me not being the creator of this bug report, so I did not continue with its upload process.

this needs to be filed upstream by someone having the issue.
