Bug ID: 408742
Summary: Ktouch crashes when closing the Course and Keyboard
Layout Editor
Product: ktouch
Version: unspecified
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: sebastian.gottfr...@posteo.de
Reporter: 1238...@gmail.com
Target Milestone: ---
Application: ktouch (19.04.2)
Qt Version: 5.12.3
Frameworks Version: 5.59.0
Operating System: Linux 5.1.9-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
I use colemak-dh, a custom keyboard layout. Ktouch doesn't recognise it and
defaults to English (US). I open the settings to try and change/select a
different course but it always crashes the application when I close said
settings window.
The crash can be reproduced every time.
-- Backtrace:
Application: Typewriting Trainer (ktouch), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
