Against this server:
    
Very often, when I connect to the server using the built-in SSH
      tunnelling, pgAdmin crashes randomly with a segmentation fault
      (segfault). I've been suffering from this problem with many
      different versions, both in the client and the server side.
    
Whenever I connect without SSH it works well. It works well even
      when I set the SSH tunnel by hand and then create the connection
      as a non-SSH connection in pgAdmin. So I believe that the problem
      resides in the built-in SSH function.
    
I've been unable to find a fixed pattern to reproduce this error.
      Sometimes it happens when you run a query, when you modify a
      column... However, it seems to be more prone to crash when you
      view data of one ore more big tables at the same time Can you help
      me?
    
Thank you for your support.
