Comment 3 for bug 728393

I'm experiencing this problem as well: Whenever an app shows the progressbar on the launcher icon (Ubuntu One in the example video) all launcher entries below it won't show the icons, up to one of those show the "launched" arrow on the left. This one will show the arrow, and all below it will show normally.

To see this problem in action, try running examples/launcher.py in libunity, and making sure that there are some non-running launcher icons below the one where the progressbar is shown.
