Bug 424467

Application: plasmashell (5.19.80)

Qt Version: 5.14.2
Frameworks Version: 5.73.0
Operating System: Linux 5.3.0-62-generic x86_64
Windowing system: X11
Distribution: KDE neon Unstable Edition

-- Information about the crash:
- What I was doing when the application crashed:
I copied a file with Dolphin, created a folder on desktop, right-clicked on it, chose "Paste one file" (the file was unexpectedly pasted on desktop).
I pressed ctrl+z to undo file copy, clicked on "Delete" button  of the confirmation dialog, then plasma crashed.

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