Description Gianfranco Polinesi 2020-05-10 03:32:20 UTC

Application: systemsettings5 (5.18.3)

Qt Version: 5.13.2
Frameworks Version: 5.68.0
Operating System: Linux 5.6.10-300.fc32.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 32 (Workstation Edition)

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

Estando en Preferencias de Sistemas > Estilo de las aplicaciones > Configurar el estilo de las aplicaciones de GNOME/GTK...
Utilicé el botón "Predeterminados" que borró el contenido de los campos de "Tema de GTK2" y "Tema de GTK3"

Subsecuentes entradas a este panel muestra el campo de "Tema de GTK2" vació y a su lado el botón para borrar temas (el del ícono del tacho de basura rojo) habilitado, al cliquear el botón el panel crashea.

The crash can be reproduced every time.

-- Backtrace:
Application: Preferencias del sistema (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
