I guess the icon file on net-p2p/azureus and net-p2p/azureus-bin haven't been updated for some time. It still uses the old icon with "A". I can't find that icon on even screenshots on the offcial website <http://azureus.sourceforge.net/img/sc/2.3.0.6/download_bar.png> Please consider updating the azureus and azureus-bin icon files. Possible icon that can be used is <http://www.kde-look.org/content/files/11415-azureus.png> It is under GPL Licence.
The following icon comes from the azureus-bin packages and I imagine it'd be the best one to use.
Created attachment 85801 [details] Azureus icon
Fixed in CVS last week. Remerging should give you the new icon.
