 I'm running 0.2.3.17-beta on Ubuntu 12.04 and I have AllowDotExit 1 in
 /etc/tor/torrc. .exit notation no longer works. This is relatively easy to
 reproduce:

 {{{
 # This works
 $ curl --socks4a 127.0.0.1:9050 http://www.torproject.org/
 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
 ...

 # The first .exit attempt sometimes works:
 $ curl --socks4a 127.0.0.1:9050 http://www.torproject.org.chomsky.exit/
 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

 # Later attempts fail
 $ curl --socks4a 127.0.0.1:9050 http://www.torproject.org.chomsky.exit/
 curl: (7) Can't complete SOCKS4 connection to 0.0.0.0:119. (91), request
 rejected or failed.
 }}}

 The following is in the Tor logs:

 {{{
 Jun 19 23:10:07.000 [warn] connection_ap_handshake_rewrite_and_attach():
 Bug: Address '[scrubbed].exit', with impossible source for the .exit part.
 Refusing.
 }}}
