We have a released Plugin on Wordpress.org - http://wordpress.org/extend/plugins/flickr-thumbnails-photostream/ which has the following headers in the PHP script.
/*
Plugin Name: Flickr Thumbnail Photostream
Plugin URI: http://community.plus.net/open-source/
Description: Generates a random selection of photo thumbnails from a given Flickr account.
Version: 1.0.1
Author: PlusNet Plc - Developer Responsible: James Tuck (Web Development Team)
Author URI: http://community.plus.net/open-source/

*/
We also have another two plugins which we use which aren't released, one of which has:
/*
Plugin Name: Wordpress News Ticker
Plugin URI: http://community.plus.net/open-source/
Description: Displays a 'ticker' tape of items within your 'Blogroll' in the category 'Ticker'
Version: 0.1
Author: Colin Ogilvie
Author URI: http://community.plus.net/
*/
as it's header.
On checking my Plugins page, I'm alerted to an upgrade for the other two plugins, despite the fact that there is no way that api.wordpress.org could know about them (and there's not an update anyway).
It would be useful if this could be fixed as it's very annoying.
