Here a screenshot from my laptop:
1. Launcher before: http://ubuntuone.com/55WM9W9Ys18Wv8rn1LntlP
2. Launcher after (not pinned) window is opened http://ubuntuone.com/5orfXO7LOtKLdAg7lxrvcB
Furthermore it seems that after the start of the system this bug occurs more often, but after some time (perhaps when some applications were already started and closed again?) the last icon stays on the right place.
