I have uploaded 0.4.47-1~ppa~lucid which reorders the icon priority a bit, to match the Desktop Notifications Specification. If you could test the package and let me know if it fixes your issue, that would be great.
There is still a chance that it may still not work. We now check first for the image_data hint, where I hope your icons are, then try the image-path hint followed by the app_icon member.
Lastly, we check the old icon_data hint, so it may still be broken if your app uses that, but also sets app_icon or image-path. If that is the case, and it still doesn't work, please enable debugging in the preferences and check ~/.cache/recent-notifications.log to see what your app is using.
I can fix it to check both image_data and icon_data first, it really shouldn't hurt anything, but I would prefer to use the priorities from the spec so that it matches the way in works in the newer gnome3 version of recent-notifications.
