KDE Platform Version: 4.11.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic i686

-- Information about the crash:
- What I was doing when the application crashed:
I unlocked the widgets, selected Panel Options, Panel Settings, right-clicked on the Show Hidden Icons arrow in the system tray, selected System Tray Settings and put a check next to Bubblemon.
Not sure, but I think the crash occurred when I clicked Apply.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
