-- Information about the crash:
- What I was doing when the application crashed:

One of the systray entries seemed to become only partially visible (the network management settings one) and I went to change system tray settings and it crashed.

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