Comment 4 for bug 502294

From experience, password-protected channels work fine when specified as "join #channel key [on source]". I'm not entirely sure about /that/, but certainly (though this is for a bot in only one irc channel) the line in my config file reading: "channels = '#channel key'" causes it to join without any trouble. This is in 1.0. I can't say anything about invite-only channels, however.
