Application: plasmashell (5.12.9)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 5.4.0-70-generic x86_64
Distribution: Ubuntu 18.04.5 LTS

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

Plasma freezes after start, but other applications works, so by using yakuake i restart plasma with this line:

`kquitapp5 plasmashell || killall plasmashell && kstart5 plasmashell`

then I clear clipboard with this:

`qdbus org.kde.klipper /klipper org.kde.klipper.klipper.clearClipboardHistory`

and while theese commands are running i start `dbus-monitor`. Idk why, but without this monitor i have to restart plasma multiple times (with first command) and clearing clipboard sometimes doesn't work

Time to time plasma freezes in same way, I've noticed that copying some large things (like big amount of logs)

The crash can be reproduced sometimes.

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