Description Vishal Biswas 2017-07-16 08:19:56 UTC 
Application: plasmashell (5.10.3)

Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.11.9-1-ARCH x86_64
Distribution: "Arch Linux"

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

In the Apps & Docs screen, I typed "open" instead of "opera" then pressed back to clear it, instead the plasma-shell crashed at that point.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".

backtrace: plasmashell-20180812-075135.kcrash
Comment 2 André Verwijs 2018-08-12 07:14:56 UTC 
Getting the same with Debian Linux
- Plasma version 5.13.2
- KDE Frameworks 5.47.0
- QT 5.10.1 
- Kernel version 4.17.0-1-amd64

when opening app menu and type random text, plasma restarts (screen tuns black for 4 second and returns again) but also sometimes crashes (not returning) 

added Backtrace as attachment..

Application: Plasma (plasmashell), signal: Segmentation fault
Comment 4 Nate Graham 2022-06-25 19:50:45 UTC 
A lot has changed since this bug was filed. Is it still reproducible for you in Plasma 5.24 (the latest LTS version) or 5.25 (the latest version, period)?
