Client spits out a trace if it cannot connect to the server

[https://www.google.com/accounts/o8/id?id=AItOawlP6DRBvIJ7NLpLWILbgzURvGbMtGEyd8U]

If the client cannot initiate a connection to the server (for whatever reason), it spits out a Python trace, which is a bit ugly:

$ bcfg2 -S https://does.not.exist

Fixed the traceback in 44f427f197c7f4e2cb4bba250450454bf7b8d179. Thanks for the bug report.
