Description Alexander Lohnau 2019-12-01 20:20:46 UTC
Application: kcmshell5 (5.16.5)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-23-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
A couple of months ago I deletes some of the existing web shortcuts because I will never use them.
Scince then there are a lot of empty entries.  If I delete them or any other entry the app crashes when I click Ok/Apply.

- Custom settings of the application:
Some of the default entries have been deleted and shortcuts for existing entries have been added.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
