I also have a konsole icon in the panel and was having an active konsole on the desktop. After closing the active konsole, I was able to move the dolphin icon in the panel without a crash.

I'm having a similar problem, I think.  I was trying to add a widget to a panel when Plasma crashed. No back trace.  I'm not sure the back trace package is installed.  When I tried to add the back trace symbols, there was an error installing the modules.
