Serverchange with // does not work

[toppa]

After login into a server I have to change the internal
server by writing for example metusalix/tmp into the
"Remote Site:" drop down list.
This is equal to the ftp command "cwd metusalix/tmp".

But FileZilla is throwing away the second / and so the
command fails.
This is what Filezilla is writing into the log when I'm
typing "metusalix/" into the "Remote Site:" drop down
list and hitting enter:

Command: CWD /metusalix/
Response: 550 Invalid Path
Error: Could not retrieve directory listing

but it should be

Command: CWD metusalix/

instead.

Filezilla version: 2.2.25

No supported at the moment, please connect to the other
server directly.
Unless I can get access to a server which supports this, I
can't implement support for UNC paths.
