/permissions crashes with rabbitmq v. 1.7.0

[therevoltingx]

I'm getting this error with v. 1.7.0 using the default configuration. Which gives guest read/write permissions:

curl -i http://localhost:9999/permissions/ curl: (52) Empty reply from server

In the erlang console: Error: {json_encode,{bad_term,{<<"guest">>,<<".">>,<<".">>,<<".*">>}}}

However, running: curl -i http://localhost:9999/permissions/vhost/root works ok.

I can reproduce this was RabbitMQ 1.7.2. Please find the crash report below.

Same happens with a POST request to /permissions to add a permission
