bookmarklet for submission of scoops only works if user already logged in

Noted on my own site, and replicated on Drigg.org

If the user is not already logged in to the Drigg site, the bookmarklet (see http://www.drigg-code.org/node/127) for submission of scoops takes the user to the user account page, with the "create a new account" tab active.
When the "login" tab is then made active and the user logs in, one is not directed to a "submit" page with the scoop information filled out. On the Drigg.org site, I am redirected to the "Published scoops" main page; on my site, I am redirected to my User Profile page. Either way, the attempt to submit an article is aborted.

All works fine, if the user is already logged in to the Drigg site prior to using the bookmarklet to submit an article.

Note that in Pligg, the very similar bookmarklet does work if not already logged in - if submitting an article using the bookmarklet when not already logged in to the Pligg site, the user is directed to a login page, and on logging in, is redirected to a submit page, with the title and URL of the nicely filled out.

On my own site, I'm using the 9/25/08 release of Drigg (drigg module release 5.x-1.36), using the Drigg/Drupal ("express install") distribution from the Drigg downloads page; with Access Permission set for Scoop submission by anonymous users (but with "Allow anonymous posting of Drigg stories" denied in the Drigg module configurations). This problem is replicated on the drigg.org site.

The bookmarklet I'm using (configured here for drigg.org) is
javascript:q=(document.location.href);t=(document.title);s=(document.getSelection());void(open('http://drigg.org/node/add/drigg?url='+escape(q)+'&title='+escape(t)+'&body='+escape(s),'',''));

The "official" bookmarklet (below, again configured for drigg.org) does the same.
javascript:q=(document.location.href);t=(document.title);void(open('http://drigg.org/node/add/drigg?url='+escape(q)+'&title='+escape(t),'','resizable,location,menubar,toolbar,scrollbars,status'));
