I recently upgraded to Ubuntu 13.10 and switched from using KDE to Unity. When I search for the program Steam in the Unity dash, it's entry (leftmost in the screenshot) does not contain any text and doesn't show the steam icon. Once I launch Steam, I have the correct icon shown in the Unity launcher. There are a handful of other applications missing icons and/or text like this.
What could be the cause? Steam has a .desktop file that worked fine under KDE.
