Bug 402294

Application: systemsettings5 (5.14.4)

Qt Version: 5.11.2
Frameworks Version: 5.53.0
Operating System: Linux 4.18.0-13-generic x86_64
Distribution: KDE neon User Edition 5.14

-- Information about the crash:
There is an empty web shortcut that I have no idea where it comes from. I tried deleting it and when I try to apply the changes the application crashes as well as its parent, which can be systemsettings or konqueror.

The crash can be reproduced every time.

-- Backtrace:
Application: Arranjament del sistema (systemsettings5), signal: Segmentation fault
