-- Information about the crash:
I use a second display for better viewing connected to my laptop. Always I startup the down panel don't show. I have to open the laptop and wait until it shows the panel and then close the lid to use the second display. If i don't do that I can't see the lower panel.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
