Icons of some notifications are not shown properly

[Allis Tauri]

I use Recent Notifications 0.4.45 from ppa on Ubuntu Lucid (10.04).
I also use Google Chrome with chromify-osd plugin (https://launchpad.net/chromify-osd) which sends notifications from web pages to a notification daemon, each with corresponding icon provided by a web url. The notification-daemon (or notify-osd daemon) displays notification with it's icon correctely, but when you open recent-notifications list, all such notifications have the same icon — from the first recorded notification of this kind.
All notifications sent from desktop apps with system installed icons are displayd correctely.
