-- Information about the crash:
Hello,
I want to report this bug, I search and I find the same so I think this backtrack will be also helpfull for dev's. I see I have double panel where is a cloak, kde menu, sys tray icons, so I remove the second. And get this errors. Before he show I has got nottification about update, so I update the packages and while packages upgrades my screen turn off, and I can't get to the console to see what is happend, logs doesn't give me a hint, I nothing have about this error. And after upgrade I have two pannles. Regads.

The crash can be reproduced every time.
