Sorry, it's on Russian:
"Буфер обмена" = Clipboard
"Громкость" = Sound volume
"Обновления программ" = Programs updates
"Подключаемые устройства" = Plugged-in devices
"Принтеры" = Printers
"Системные уведомления" = System notifications
"Батарея и яркость" = Battery and brightness
"Сети" = Networks
Comment 4 Igor Zhuravlov 2018-11-23 11:10:29 UTC
I've worked it around by deleting Klipper's log:
1) reboot up to Login Screen (SDDM)
2) switch to text console and log in as root
3) cd /home/user/.local/share/klipper && mv history2.lst history2.lst.bak

One of previous steps was to delete /home/user/.cache , but it didn't help.
