-- Information about the crash:
<In detail, tell us what you were doing  when the application crashed.>
I just clicked by LMB into klipper icon placed in systray. Previously some text was copied into clipboard.

Sorry for this not much useful backtrace, but this is only one thing I got after crash.

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