sftp:// does not work when SSH client has "ControlMaster" and "ControlPath" defined

[Anderson]

Binary package hint: konqueror

SSH can open several login shells to an unique server by using an unique connection. The first SSH client launches a connection and listens an UNIX socket in a known location and the following SSH clients connect to that UNIX socket instead of opening a new connection to remote server. This feature is useful when using password authentication in SSH: you only need to type the password at the first time.

I am using this feature in my system. In order to do that, I put the following lines below "Host *" in /etc/ssh/ssh_config:

ControlMaster auto
ControlPath ~/.ssh/%r@%h:%p

But sftp:// did not work. In Konqueror, when trying to browse a remote server which already has an open connection, it waits, waits and then gives up, informing a fail during SSH conversation.

sftp:// works well if it is the first connection to the remote server.

I'm using konqueror 4:4.1.1-0ubuntu2 in Ubuntu Intrepid x86.

Steps to reproduce the bug:

# Put "ControlMaster" and "ControlPath" lines in /etc/ssh/ssh_config, as I did.
# Type in a terminal:

$ ssh <user>@<remote server>

# Type in another terminal:

$ konqueror sftp://<user>@<remote server>/

Fix committed for KDE 4.4. Since it is part of a rewrite of the sftp:// kio slave, we will unfortunately not be able to backport the fix.

Fix released to lucid. (Will be a bit before it actually shows up due to a few build issues)
