For some reason, quite a few launchers on the Unity Dash don't work after upgrading to Oneiric 11.10. They worked fine in Natty 11.04. Some launchers do work, but a lot don't. After doing unity --replace in a terminal, I notice the following error appears every time I click a launcher that fails to work:
