[wp-hackers] Wordpress uploader bug, and question

[Luke Bryan]

Greetings,

I recently found an exception in Wordpress 3.5's new uploader javascript:
Edit a gallery in a post, and after clicking update, it gives an
exception: TypeError: router is null

I saw a bug on trac about "Router is null" exception, though it is
marked fixed. Is this the same bug, or should this be reported as a
new problem?
https://core.trac.wordpress.org/ticket/22710
I think this might have been part of a problem I was having earlier
with catching some events and modifying parts of an upload-form.

I was also curious whether or not there are any plans for adding a
filter/hook for function wp_ajax_query_attachments() in
ajax-actions.php, for adding images/items to the ajax response used by
the uploader? Or is there a javascript/backbone hook for this type of
functionality?

Best regards, and happy new year,
Luke
