-              rewrite ^(.*)$ $1$stripped_params permanent;
+              rewrite ^(.*)$ $1?$stripped_params? permanent;

1. Missing '?' to separate uri path and arguments.  Note that $args 
doesn't contain leading '?'.

2. Without trailing '?' nginx will append original arguments to 
resulting rewrite uri.
