At svn rev 1292387 this test works.  At svn rev 1292388 it does not -- and it looks like this problem has persisted to today.

I will include in this comment two scripts -- a large one that I use to start the broker, and a teensy one that I run qpid-stat with.

When qpid-stat succeeds, it looks like this:
{


    Connections
      client-addr                     cproc      cpid  auth        connected  idle  msgIn  msgOut
        =============================================================================================
          127.0.0.1:6667-127.0.0.1:50224  qpid-stat  9863  guest@QPID  0s         0s     208    263
}


When qpid-stat fails, it looks like this:
{
    Failed: ConnectError - [Errno 111] Connection refused
}
