My guess: you are running a German Windows version, which will give
you a German error message, with non-ASCII characters, when the
connection fails. This error message is encoded in the latin-1
('western european') encoding, and decoding it as plain ascii fails.
Feel free to substitute German for French, Spanish or any other
language that might have non-ascii error messages.

Is this the same as http://sourceforge.net/tracker/?func=detail&aid=3153555&group_id=93107&atid=603138 ?
This is an old problem. Once I tried to deal with that but could not reproduce the error on purpose. How to create a test environment for such network errors?
