Comment(by rransom):

 I just saw that keb had attached new logs.  (Trac doesn't send e-mail
 notifications for new attachments.)

 The important lines are right at the end:
 {{{
 Dec 13 03:07:09.000 [debug] connection_handle_event_cb(): event occurred
 on conn 75 (Exit connecting (marked for close))
 Dec 13 03:07:09.000 [err] connection_handle_event_cb(): Bug:
 connection.c:2971: connection_handle_event_cb: Assertion
 connection_state_is_connecting(conn) failed; aborting.
 }}}

 So an exit connection was marked for close before it had finished
 connecting.  Can we just ignore _CONNECTED events for connections that are
 already marked for close?  Can we ignore ''all'' events for connections
 that are already marked for close?
