Application: plasma-discover (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.15.0-33-generic x86_64
Distribution: KDE neon User Edition 5.13

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

Yo estaba intentando actualizar kde neon, primero desde la version user 16.04 a la version gitstable, para luego intentar actualizar a la version 18.04.

Las imagenes 18.04 de finales de agosto funcionaban bien pero las nuevas del 6 de septiembre el instalador se estropea cuando empieza a instalar el sistema. Esto me pasa con las versiones user edition y developer edition gitstable. Por eso he tenido que instalar la version 16.04 que es la unica que funciona.

Gracias.

The crash can be reproduced sometimes.

-- Backtrace:
