Encoding of img tags for inline images has changed in 3.2.0

I am developing the camosslimageproxy extension, and it has been noticed that the extension does not work properly on a v3.2.0 board.

I have isolated the issue to being that when an in-line html image tag is written to the template array in 3.1.x it has the format:
<img src=\"http://i42.photobucket.com/albums/e318/adnil11/Vince/oiu.jpg\" class=\"postimage\" alt=\"Image\"/>

but in 3.2.0-RC2 it is:
<img src=\"http://i42.photobucket.com/albums/e318/adnil11/Vince/oiu.jpg\" class=\"postimage\" alt=\"Image\">

The difference is the /> or > at the end.

I guess that this has changed with the change of BBCode engine, I want to check whether it is expected or a bug, so I know whether to modify the extension source code or not.
