Lounge smartproxy exception causing cluster views to fail

["Coffman, Timothy A" <ti...@Vanderbilt.Edu>]

I have configured a Lounge cluster with 3 shards.  I can view all the documents in the cluster with no problem through Futon.  However, all my view requests are failing.  I put twistd in a debugger to see what might be causing the error, which looks like "'can only concatenate tuple (not "str") to tuple'".  What I got is below.  Any ideas?

[tcoffman]$ curl -v http://localhost:6984/clinical/_design/clinical/_view/all
