/users/nonexisting and /vhosts/nonexisting crashes

[amr]

$ curl -i "http://localhost:9999/users/nonexisting" returns: "curl: (52) Empty reply from server"

And the following error in Alice shell:

(alice@pipeline)1> Error: {function_clause, [{mochijson2,'-json_encode_proplist/2-fun-0-', [{ok,400,[],{"nonexisting",<<"not a user">>}}, "{", {encoder,null,false}]}, {lists,foldl,3}, {mochijson2,json_encode_proplist,2}, {rest_server,jsonify,1}, {rest_server,run_controller,4}, {mochiweb_http,headers,5}, {proc_lib,init_p_do_apply,3}]}

An identical behavior can be seen with /vhosts/nonexisting
