-- Information about the crash:
Anytime System Tray Settings (ALT+D,S) is used to make changes to the system tray options, the plasma workspace panel crashes and then restarts itself.  After the workspace restarts, it resets the workspace back to it's KDE original default (what the screen looks like after a fresh install).

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Aborted
