Comment 9 for bug 91116

In my opinion there is no bug, and there is no need to remove seahorse (although removing seahorse indeed removes the odd behaviour). Your problem is that you must have a bogus password set up in seahorse.

Open Applications/Accessories/Passwords and Encryption Keys. In "My personal keys" you probably have a dodgy secure shell key which is causing the odd behaviour. Delete it ruthlessly. Now you can add a brand new secure shell key (Key/Create New Key) if you wish to login ssh sessions automatically (it does work flawlessly). If there are no secure shell keys stored in seahorse, then you'll have to type your password everytime you issue "ssh" from the console.
