Uploading files in IE7

I don't know if you are considering this as a but:
I'm using the latest svn version of the Kaltura media component for buddypress (rev 302198) and I'm having trouble uploading media in IE7. This is probably caused by an extra comma on line 140 of \themes\media\upload.php
When the comma is there, IE7 wont display the "Media uploded" message after the upload is complete.

By default the code looks like this:

var data = {
action: 'media_upload',
rt_entry_id_list:rt_entry_id_list,
rt_entry_media_type:rt_entry_media_type,
rt_entry_group_id:'<?php echo $groups_template->group->id;?>',
album_name :album_name,
visibility : visibility,

};
