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".

I noticed a second crash when: 1. Create a custom Course, e.g. "My testing words." 2. Click on the Title, Description, etc. Anything that involves editing a text field, after the course has been created and is in the list with the default courses. 3. While cursor is in text box, close the Course and Keyboard Layout Editor Window. 4. Crashes similar to this.
