Description

Bug discovered by Petr Matousek.

Attempting to validate the broker using the 'ssl_trustfile' parameter results in the following crash:

1. ~/qc2_drain.py -b amqps://$(hostname):5671 "amq.direct/test" --connection-options " {ssl_certfile:/var/lib/qpidd/qpid_nss_db/client.pem, ssl_trustfile:/var/lib/qpidd/qpid_nss_db/rootca.crt}

   raise SSLError("This version of Python does not support verification of the peer's certificate.")
   NameError: global name 'SSLError' is not defined

This is due to the fact that older python releases do not define the SSLError exception.
