pgAdmin3 backup over ssh tunnel

Hi all

I use pgadmin 1.22.1 which is connected to remote database over ssh tunnel (the tunnel is created by pgadmin).
However, when I try to make backup it instead of working with database over ssh tunnel tries to connect to localhost database.
How to fix it? It this bug fired?

I have the same problem is it is described here  http://stackoverflow.com/questions/32398311/pgadmin3-backup-over-ssh-tunnel

Please, any hint.

Best regards, Alex
