User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5
Build Identifier: "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2b3) Gecko/20091115 Firefox/3.6b3

If no file is picked on a file upload form, the empty content of the file is not sent. version 3.5 would have something like:
-----------------------------9849436581144108930470211272
Content-Disposition: form-data; name="my_name"; filename=""
Content-Type: application/octet-stream


-----------------------------9849436581144108930470211272

In version 3.6b3 the whole above section is missing.

Reproducible: Always

Steps to Reproduce:
1. Go to a web page with a <form method="post" enctype="multipart/form-data" ...> with a standard file upload form with <input type=file...>
2. Submit the form without choosing a file

Actual Results:  
The POST data will be missing the section with the form-data corresponding with the file upload's data 

Expected Results:  
The POST data should contain empty data for the file, with an empty filename
