Icons are occasionally disappearing from the panel next to Kickoff Application Launcher. Once they are gone, they are gone.
I had added a terminal yesterday, today it is not there.
After a few reboots even the Dolphin icon has disappeared. [I also do not find one under Panel Options > Add widgets that corresponds to the preexisting Dolphin]
This behaviour was seen even under 2009 with KDE4.
How to get the Dolphin icon back?
