Sentry Crash Report:
Attachments: New crash information added by DrKonqi

Description masterdesky 2021-05-08 11:51:51 UTC 
Application: plasmashell (5.14.5)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-16-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

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

I've noticed that sometimes, when I type something into the search bar and the suggestions starts to updating, the taskbar crashes, disappears, but quickly restarts again. It happens pretty rarely and randomly, but I thought it's worth to report it.

The crash does not seem to be reproducible.

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