-- Information about the crash:
I used nvidia-settings to switch on/off an external monitor. When I switched back to laptop only, the panel was too wide. I tried to adjust it, but it didn't work. I tried removing the window list applet so the system tray would come back into view. When adjusting the widgets, it crashed.

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