When creating a new server connection through SSH (SFTP) and editing the entry, the port is not shown in the gui. 
When pressing "OK" without the port shown, it is removed from the server address entry and the default port is used.
However: the port seems to be stored and used at later times when adding it to the server address (e.g. "my.server.com:9876"). In this case, it is also not shown when editing the stored server connection, but it seems to be stored and used.

Also, very strange behaviour encountered while trying to work arround the bug:
 
I've created two connections using the same server and port
- ConA using the server:port notation in the "server" edit field
- ConB using only the server name in the server edit field and the port in the "port" edit field.

Closing and reopening gnome commander, ConB doesn't work; ConA works. Closing ConA and trying to open ConB --- now ConB WORKS (until gnome-commander application closed and opened again...). Something smells fishy with the way the port is handled...
