Bug 439642

Application: plasmashell (5.22.1)
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.83.0
Operating System: Linux 5.12.13-gentoo x86_64
Windowing System: X11
Drkonqi Version: 5.22.1
Distribution: "Gentoo Base System release 2.7"

-- Information about the crash:
- What I was doing when the application crashed:

I tried to "Open Klipper on mouse posiiton" and plasmashell crashed. The Klipper menu did not open and the same bug occured several times after restarting plasmashell manually.

The reporter is unsure if this crash is reproducible.

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