Description siralexgil 2020-03-22 17:31:17 UTC

Application: systemsettings5 (5.18.3)

Qt Version: 5.14.1
Frameworks Version: 5.68.0
Operating System: Linux 5.5.10-arch1-1 x86_64
Windowing system: X11
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Opening system settings > workspace behavior > desktop effects > translucency  > configure
- Unusual behavior I noticed:
It works OK if system language is set to English but chashes if it's Spanish.

The crash can be reproduced every time.

-- Backtrace:
Application: Preferencias del sistema (systemsettings5), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".

New crash information added by DrKonqi

systemsettings5 (5.18.3) using Qt 5.14.1

- What I was doing when the application crashed:

Opening translucency panel in KDE settings.
My KDE Plasma is in French Language (seems related because other report the same bug with KDE in Spanish Language)

[kcmkwin] Make dialog non blocking

Summary:
It's invoked from QML.

Nested event loops invoked directly from QML is asking for crashes.

Test Plan:
Opened KCM
Opened dialog for some settings
Window was still modal as before
Settings were saved
(though they didn't seem to be applied..maybe another bug?)

If it gets more dupes, I should probably backport this.
