[systray] Some panel icon dies, leaves white box

Bug Description

Binary package hint: unity

Some sort of panel icon is leaving white boxes behind in the Unity panel. I think that this might be the "I am indexing" tracker icon, but I'm not sure; I've seen that appear and disappear, but I've never managed to see anything actually die and leave the white box. See attached screenshot.

I occasionally see this type of white icon and clicking on it crashes unity

Using this as a tracker to make sure it doesn't happen in latest Unity when we get panel support.

This bug was fixed in the package unity - 3.4.4-0ubuntu1
