That's odd. I tried running this snippet, connecting from a Windows XP
Pro box to a RHEL box:

ftp = FTP.new(host, user, passwd)
ftp.chdir('/totally/bogus')
ftp.close

It raised an exception for me:

C:/ruby/lib/ruby/1.8/net/ftp.rb:243:in `getresp': 550 Failed to change
directory. (Net::FTPPermError)
        from C:/ruby/lib/ruby/1.8/net/ftp.rb:251:in `voidresp'
        from C:/ruby/lib/ruby/1.8/net/ftp.rb:274:in `voidcmd'
        from C:/ruby/lib/ruby/1.8/monitor.rb:238:in `synchronize'
        from C:/ruby/lib/ruby/1.8/net/ftp.rb:272:in `voidcmd'
        from C:/ruby/lib/ruby/1.8/net/ftp.rb:677:in `chdir'
        from ftp_test.rb:5

Can you tell use more about the platform you're connecting to? Maybe
it's not sending back an expected (or any) response with chdir. You
can tinker with FTP#sendcmd as well to see how it behaves. Or, just
ftp manually, and try to chdir to a bogus directory and see what it
does.
