Comment 48 for bug 72468

I seem to have stumbled across the cause AND solution to my icon problem. After applying the current recommended updates I had to reboot the system, and at the login screen I decided to look and see if the Options at login had changed from 7.04 ubuntu. Under Sessions I was offered to use the previous session or change to another. Although I assumed that I had been using Gnome, I selected Gnome anyway, and was then asked if I wished to make the change permanent as I had previously been using Xclient. I was unaware I had been using Xclient and had not been given a choice previously to select it, but once the Desktop came up I immediately noticed the Trash icon was showing full, and is now displaying how many items are contained in the trash when I point to it.
In my case this problem is now cleared, and perhaps some others may benefit from what I found?
