Bug 388983

Application: kdeinit5 (5.11.90)

Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.14.11-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Trying to chage the default web shortcut for konsole to duck duck go.

-Steps to reproduce:
Open a konsole window
Right click, select "search for", open the "Web Shortcuts"
Either Click "OK" or "Cancel", no changes are necesary, even if you do they are not saved.

Doing the same from Systemsettings>Shortcuts>Web Shortcuts as well as running the module directly from Krunner does not trigger the crash.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings Module (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
