Bug ID: 411006
Summary: Endless loop "can't show the preview of the keyboard
layout"
Product: systemsettings
Version: 5.16.4
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: systemsettings5 (5.16.4)
Qt Version: 5.12.3
Frameworks Version: 5.61.0
Operating System: Linux 5.0.0-25-generic x86_64
Distribution: KDE neon User Edition 5.16
-- Information about the crash:
- What I was doing when the application crashed:
I was looking at keyboard layouts; I'm Italian, but with a US International
keyboard layout. I was wondering if there was already a keyboard map with
accented vowels, needed when I writein Italian.
- Custom settings of the application:
I selected the "International Phonetic Alphabet" layout, then click to see the
preview.
A popup dialog said "I can't show the preview; I close it, than it apeears
aghain and again, endlessly
The crash can be reproduced every time.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
