ajax data cannot send empty array

[tenev@…]

An empty array or an empty object cannot be send via jQuery.ajax()

to reproduce:

$.ajax({
   url: 'test.php',
   type: 'post',
   data: {empty:[]},
});

In this case the "empty" array is not sent to the server.

I can reproduce this bug again in 1.9.1.

In Javascript console, I do:

$.get("/items/do_work", {abc: []})

On server end (Rails), I get:

Started GET "/items/do_work?def=&ghi%5B%5D=3" for 127.0.0.1 at 2013-02-10 10:46:10 -0800
Processing by ItinerariesController#start_info_update as */*
  Parameters: {"def"=>"", "ghi"=>["3"]}

Their bug report was not unrelated and I am running into the same problem. jQuery 1.9.1 is not able to send "empty" objects like the following one via an ajax-request.

{abc: {}}
